Hi George, What happens in crtbank.asm is under your control when you write your own. So you can get the correct value in PSBANK. But what will go wrong is the LSW of the physical/virtual address. The linked code will jump to 0x0000 when it needs to go to 0x10000 instead of the bank at 0x8000.
Post-processing is probably easy with a tool like srecord (srecord.sourceforge.net).
