I agree with Yankee and Leinad: there's no reason why the two games can't coexist peacefully. Perhaps we could even appoint ambassadors and conduct diplomacy between the two.
I mentioned this on AAD when an AAD sim was discussed and I think Earl was somewhat interested, but it got shot down amongst bemoaning how a lack of term limits destroyed the game. Really? We are fast approaching ten Senators having left the chamber since February. The only seats that have not changed hands in that period are Polnut's (Retiring) and Cris' (elected in December).
Anyway back on point. An interactive foreign policy that was more than just what the GM generated would add a new dynamic that is completely novel and original. I would recommend the mock Parliament go for Albion instead of Atlasia redux British style. That way we can have a post UK Britain and a Post US America.
You could do a restart here, even if not a full one, and thereby clear the foreign policy realm to completely make way for this new dynamic.
