Sure, after the package passes, groups can try to form separate coalitions to pick things out of it; there are methods to protect them, generally (such as putting together a similar coalition to put up a trigger bill that deletes the parts the other groups want to protect conditioned on the other repeal passing, undermining its support.)

Yeah, real world politics is generally not about finding stable equilibria, as much are the things most easily amenable to theoretical analysis.
