Whilst I think the performance hits kill this stone dead, I wouldn't expect any Endian bugs. Much initial work was done on older MAC's which are I believe BIG endian. I have a Sun Ultra 60 SPARC workstation, also big endian and run Hercules on that with no issues. There again I have only run the OS's that are legal in my domain on this, and rely on the generosity of list members for access to zVM Systems so the latest and greatest may not work...
