Interesting questions! I don't know G2 (or his ministers) well enough to say. If there had been, say, 25 years of closer relations between the countries, maybe? If Amelia is willing to try to get concessions out of her father the way Fritz used EC to try to get concessions out of his father, and if G2 is susceptible to Amelia's intervention, maybe.
Fritz and G3 I'm much more skeptical about. Maaaybe if the Seven Years' War had been less devastating to Prussia, and if that was due in an undeniable way to help from Britain? But Fritz was never known for gratitude toward his allies. I can see him helping out G3 if he expects to get something out of it; when he's already gotten what he wanted and is nearing the end of his life, what's the point? He's got problems closer to home to worry about.
The first question that comes to my mind is: helped out how? Going in person? Not a chance. Shipping mass troops overseas where he couldn't personally oversee them? Seems OOC. Money? I don't know, was he in the habit of giving money to his allies when he could use it on opera houses? (Half rhetorical, half serious question: I have an impression of Fritz as reluctant to part with money in general, but there may be examples I'm forgetting where he subsidized other countries to get what he wanted. But again, what does he want here?)
Writing letters to other European monarchs about how democracy was the scourge of the earth and the colonies owed obedience to their British overlords? Yeah, sure, but I don't think history changes much. (While I would never expect him to support democracy as a system of government, I'm curious if you know what his RL opinions were about specific American reforms.)
So that leaves shipping officers overseas to help out the British against the likes of von Steuben and Lafayette (I have to assume Fritz's acid letters to France just made the French-American alliance stronger, if anything). That I could see Fritz doing. He doesn't have to fear mass desertion among his officer corps nearly as much as the rank and file, the cost-benefit ratio is good as long as he has enough officers at home to make up for the losses in the Americas (he never minded losing his officers in battle), he gets to take some credit if the British win, some of his officers presumably come home with more battlefield experience, and he gets goodwill from Britain at pretty low cost.
If we're talking about changes caused by the personalities involved in the double marriage, well, Wilhelmine is long dead and was never queen, and Fritz presumably keeps Amelia as far from power as he can, the same way he did his mother. To the extent that she tries to influence politics anyway, and to the extent that she succeeds, to that extent I predict a less successful marriage.
So, while I see Fritz potentially being 5% more chill in his overall personality because he wasn't forced into a marriage he hated, and at least 50% more willing to make an effort within the context of that marriage, if you assume everything else stays the same, it's hard for me to believe it affects his foreign policy *that* much.
Open to other arguments, though! I am definitely not up on the political nuances here, and am arguing almost solely from Fritz psychology.
