Additionally '60 misses ... also addressing modes for integers.

No it doesn't, at least last time I checked.

Few integer 64bit math operations need to be emulated. Also some special instructions like MOVEP/CHK2/CMP2/CAS2 are not implemented on hardware (those instructions are rarely used anyway). CAS generates exception on misaligned EAs. That's not "missing addressing modes for integers" IMO. 060 does all addressing modes of the previous 68K CPUs.
