Great list, and very plausible. There was no specific letter designation for the Iranians or the Israelis, so you could say they just bought basic F-111As, but modified with customer-specific avionics and weapons capabilities. The only country that ever had its own specific designator was Japan-until the '90s (A-4AR for Argentina, F-15I for Israel, F-15S for Saudi, etc.).
I went that road to signify the variants that would be sold to others. I have also noted that the Saudi and Iranian Varks are not as advanced as the Israeli ones - that's to not have them have an epic meltdown. I would suspect that the Iranian units would have a hard time flying after about 1995, just because of the parts embargo, same as with their Tomcats. In this world, Iran might take the Russian offer to re-engine all of their F-14 and F-111 aircraft. I'm envisioning the Israeli F-111s being used for the first time in the Yom Kippur War, with them seeing lots of use blasting Syrian and Egyptian facilities though probably with a bunch falling victim to the SA-6s used the Arabs. I would also suspect that once the Israelis know just how good they are, that they become the backbone of Israel's strike ability with their air force, and they get used in the operations against Osirak and the PLO Headquarters, among others.
The above is why I shyed away from a SAAF version unless as suggested However if the Vark is still very much alive by 1994 with planes still being manufactured in say 1985 or 86 then just maybe you could have ex-USAF or ex-RAF refurbished planes in SAAF. Maybe as part of the refurbishment they get locally producted electronics?
South Africa's bugbear with its aviation industry was electronics, their local fighter projects were slow because of that more than anything. They could operate the F-111, but after 1994, when they don't have to worry about deterrence against outside threats, why would they? Post-apartheid South Africa has better things to spend their money on. I just don't see the SAAF ever operating the Vark, because during apartheid getting the airplanes would be hard (and the SAAF mostly used European equipment in any case) and maintaining them harder still, and after apartheid there isn't the need.
Now that's what I call a detailed list- lots of work in getting it together. How about adding some dates to versions that never happened?
F-111A: 291 (including 17 prototypes) Built by General Dynamics in 1967-72. 50 aircraft converted to EF-111A Raven standards between 1975 and 1981, 17 sold to Australia and converted to F-111C standard in 1983-85. 133 aircraft produced to F-111IR/F-111IS (80 Iran, 48 Israel, 5 prototypes) standards in 1970-72.

Approved by USAF in 2001 as a rebuild program for USAF F-111F models, 76 have been converted as of 2012, with 14 more to go. New-build versions approved in 2005, with 54 new-build airframes approved, first produced in 2007. Final example expected to be delivered in 2013. Germany, Japan and Australia have also proposed to rebuild their F-111 fleets.
As for 2012, the total F-111 count in operational service is:
United States Air Force: 123 F-111R, 14 F-111F, 38 EF-111A
Royal Air Force: 41 CF-111K
Royal Australian Air Force: 33 F-111C, 19 F-111G, 8 EF-111SA
Royal Canadian Air Force: 85 CF-111BE
Japanese Air Self-Defense Force: 62 F-111J Kai
Luftwaffe: 22 F-111FE
Israeli Air Force: 31 F-111FI
Royal Saudi Air Force: 26 F-111SA
Argentine Air Force: 14 F-111AR
Islamic Republic of Iran Air Force: Unknown F-111IR, expected to no more than 15
It should be noted that several of the main users aim to replace their F-111s. Canada and the United Kingdom have asked to purchase the F-22 Raptor for interceptor and air superiority duties. Australia, Japan and Germany plan on keeping their F-111s from some time to come, and all three have been offered the F-111R rebuild program.
All of the above nations except for Iran and Japan used their F-111s in the Gulf War, in the case of the Luftwaffe pulling off its longest attack mission ever, flying from Neuberg an der Donau in Bavaria to strike targets around Basra in Irag on January 19, 1991, and doing so again several times during the war, supported by their tankers and those of the Luftwaffe. Canada set a record for the longest tactical mission ever, flying a strike mission against Rwanda militia positions on July 15, 1994, from CFB Gander, refueling three times in each direction, with tankers operating from the Azores, Akrotiri and Nairobi, where eight CF-111BEs bombed and destroyed the RTLM radio station and Rwandan Army headquarters in Kigali, Rwanda, in support of the Canadian intervention force in Rwanda - to this day, the "Messiah's Trident" missions remain the longest missions ever by tactical fighters and the longest fighter missions ever by the Royal Canadian Air Force. Australia's F-111C and F-111G aircraft struck Indonesian positions in support of East Timor's independence when Indonesia attempted to take it back in 1999, and four RAAF F-111Gs destroyed a Jemaah Islamiah terrorist training camp on the island of Borneo in the aftermath of the Bali bombing in January 2003. Argentina's F-111ARs were widely used by the Argentines in their war against the UK for control of the Falkland Islands in 1982, with them suffering 14 shot down by RN fighters but destroying three Royal Navy vessels and damaging five more in the process, as well as providing air support in considerable amounts to Argentina's troops in the Falklands. Into the 21st Century, the F-111's incredible speed and ability to fly low combined with its long range have made it a powerful strike weapons, a fact proven in numerous wars and interventions from Vietnam to Libya.
