I don't think it would work as the 'mini reality' that each one makes only works for itself. In Star Wars your have 'the force' in Xmen you have mutants (and some magic.) When you cross over and mix too much it just becomes silly.
But honestly, I don't expect much from the new Star Wars films. The first one (IV) was great, and the world, but I think they should have chosen a better director like Jackson, Alfonso Cauron, Ang Lee or even Uwe Boll.
