How about making a "full" RPG parody, mocking all the (over-)serious RPGs out there?
I mean, getting "serious" is a difficult subject, especially since the Divinity universe/franchise isn't all that well constructed as a serious world after all. While containing some serious matters Larian games were always a bit "silly" and funny. Maybe it's time to really build on that special competence, at least in one of the upcoming games...
I would greatly embrace one deep, a bit more serious RPG along the lines of DOS (but even improved) and one just-for-fun PRG, taking the piss out of all the fantasy/sci-fi/steampunk/cyberpunk/horror/whatever stereotypes and clich馥s we know from other games, movies, books and television without any need or aspiration to be serious at all. That would be the game for which Larian finally had the opportuniy to fully live out their crazy ideas without fearing a bad conscience and without making compromises. Just like e.g. Obsidian did with their South Park RPG lately.
