Changing the character PSA's will typically have adverse affects and likely cause freezes unless the PSA you use has been made for use with Project M.
Stages should be fine to swap around.
Swapping out the menu will probably freeze the game unless the menu has been made with a Project M version. This is due to Project M having additional menu assets that Brawl menu screens do not have.
