Well I hope you enjoy your low takeup. Nobody is going to switch to a disassembly which has radically been changed and is going to confuse people. If you're not going to reference them inside the disassembly, create a text file that's provided with the disasm with the major label changes and update the equivalent subroutines table. This would give some guidance. Then again, maybe a global labelling scheme for both disassemblies could be looked at.
