I think the current spanish policy could have been reinforced by the Revolt of the Barretinas. If anything, Catalonia was not ready for war.
There a lot of butterflies from the current chapter:
- No need to have a field army of 9,000 under Noailles in Catalonia. They are released to serve elsewhere.
- There is no need for Humieres to have a 24-32,000 army in Flanders.
- With James having a 7,000 Catholic Army at his beck and call, I don't see William sending 6,000 men (the theoretical number they should have been in OTL was 10k) to the continent under Churchill. He needs to keep an experienced field army in England proper, while strengthening Scotland as well. While keeping an army in England, he needs to start making plans to invade Ulster as well.
- The Emperor doesn't receive 2500 Catholic Irish soldiers as in OTL.
- Waldeck's OTL army is released as well. If we exclude the allies, the States-General's portion of his army was perhaps 12,000 (it started in 1689 with 7000 men).
- It won't be very plausible now for Liege to join the Allies. Liege raised 6,000 men that were used in garrison duty, releasing a similar number for field army duty.
- The spanish Army of Flanders of some 10,000 men is lost for the Allied OOB.
- Lastly, the Armada del Mar Océano is not in the war. In OTL it had concentrated 15-20 warships in the Mediterranean. Likewise there are no Spanish and Neapolitan privateers praying on french trade. I don't count the 27-29 galleys of the spanish monarchy. Moreover the Flanders Armada (4 galleons, 9 frigates, 2 pataches in 1685) stays at port. Overall, the French can further concentrate their naval power in the Channel.

As you can see, the ATL developments allow the French to concentrate their forces, while the League has fewer troops and a worse strategic position. The French now have the numbers to focus on what they considered the main theater: the Rhine. Having said that, I sincerely doubt that the French can spare the resources to invade England along with the 7,000 Jacobite troops. What I consider as more plausible, it so send reinforcements to Tyrconnell, quite possibly a somewhat stronger french expedition than in OTL, along with the Irish Regiments. I think it might be plausible to send the Scottish Jacobites to reinforce the Bonnie Dundee, prolonging his struggle.
