PC:WI HMS Vanguard refits in the mid 60's & mid 80's

Assuming there was the money and will even then its gonna be hella expensive.

Cheap option.

Remove the 5.25's entirely, add 2 x Sea Cat on each side. remove the 40mm mounts as tehy are not needed (how wrong that is!) and update the electronics. And leave it at that.
 
Firstly avoiding the scrapping of HMS Vanguard in the early 60's.

Instead have her refitted out like HMS Blake, C3 etc and by removing the rear pair of main guns and installing a hanger and flight deck for a section of SeaKing HAS 1/2's

Then in the mid 80's have her again refitted in the same way as the USN's Iowa class with Tomahawk Cruise missiles etc.

How effective would these refits be?

How effective would she be in the 1982 Falklands conflict and Gulf War 1991?

Would the RN be able to afford and run this ship?

To answer the questions...

How effective: In the top 5 world's most effective battleships, that is to say a massive money sink that the UK (unlike the US) cannot afford. All useful missions could be accomplished more cheaply in other ways.
Effectiveness in Falklands war: has 15 inch guns and some helicopters: only real role that can't be accomplished in OTL is heavy shore bombardment and this is not really needed, although it might marginally reduce British army casualties. Possibly reduces naval casualties too by reducing the weight of attack on other ships, but on the other hand it is likely to attract the Argentinian air force and could be sunk with very heavy loss of life.
Effectiveness in Gulf War: totally redundant
Could the RN afford it: Not without a magical money tree, and it would have to be a very fruitful tree for the opportunity cost to be worth it even then.
 
Perhaps the biggest deterrent isn't the money itself, rather British defence policy, what is the Vanguard going to do between 1957 and 1968 when the Defence policy is Limited War East of Suez? What about from 1968 when Britain is a peripheral NATO power with no world role?
 
Even in ASB scenario where the Royal Navy gets a magic money pit I think they would rather the prestige from a full deck aircraft carrier than a battleship.

There's a Britainwank ASB timeline floating around somewhere where Britain get a Stargate in the 1800s. They pay for ww1 and ww2 from gold received through the gate and have an interstellar empire (though no one on earth outside highest levels of British government or military knows about the stargate). That Britain still doesn't keep Vanguard (even though they built it at the same time).

A Britwank ASB timeline where they get a Stargate? What the bloody hell is this shit. (Pardon my Anglo-Saxon)

But I do agree, any realistic and rational being would realize that Battleships are a thing of the past (as is shore bombardments, honestly we have aircraft that can tag targets further than a ship could.) A Vanguard refit would be a waste of money and resources.
