That's not undecidable in principle - compute governance is a thing. The more likely sticking point is that the two sides might be soured on the deal once they realize how much oversight they'd have to give to the other side.
Would this be similar to the deal of "we'll offshore all our manufacturing to you and you'll become a free, open, liberal democracy with open borders and multiculturalism?" Because I remember how that deal turned out.
That last part was never important. Trading partners very rarely go to war. There just isn’t much in it for either party. Close cooperation and dependency is actually quite important here - liberal democracy or no.
