The ABIs have some other differences. The largest difference between the ABIs is how indirect-calls (and, thus, function pointers) work. There are some other more-minor differences, for example, some of the call-frame offsets are different.  It still might be possible to unify the support (we certainly have one backend in LLVM for both), but it's a bit more involved than just switching the endianness.
