When porting from PPC to another ISA, recompilation of all binaries would have to happen irrespective of endianness. That's a no-brainer. The real issue would be code that's not programmed in an endian-agnostic way, resulting in a non-working or buggy binary after recompiling to an endianness-switched ABI.

I fail to see where bit swapping would be required with a MorphOS compiled for a little-endian ABI.
