Someone else needs to also confirm this (since I havent been on here in quite a while), but I am fairly certain that as long as you have NEVER installed MJB, you can switch around anything you want without the worry of bricking. Before I updated to MJB I went back and forth several times trying different 4.1.1 and 4.1.2 roms. And also tried a few different 4.3 roms (on MJ2 and also back to MG2) before going to MJB.
