The M6 could be a FF MILK in the M5s formfactor.
The EF-M can theoretically support FF glass, but there is
zero chance the M6 is FF in an M5 form factor.
1) Branding would be a nightmare as M6 as you'd have crop on either side of that 6 number. Why would 6 be a logical identifier for FF? I'd see a new brand name/level altogether for FF mirrorless, perhaps EOS 5DM or 6DM (if highly based on a current FF SLR body design), EOS X (if not), etc.
2) Canon would make a HUGE deal about their first FF mirrorless rig. Huge, I say. No chance this would be lumped in with two other major releases like the Rebel refresh, the 6D2, etc. I'd see the first mirrorless FF rig getting an open 3-6 months of no other Canon releases adjacent to it to make it Canon's sole message / focus over that time.
3) If they crammed a FF sensor into such a tiny (M5-like) body, it would have to be terribly nerfed feature-wise as there wouldn't be room for larger buffer, second DIGIC chip, standalone metering chip, all the I/O connections, etc. Controls and ergonomics would also suffer -- no room for FF expectations of buttons/wheels and the tiny grip would suffer with larger FF lenses. And
heaven help the battery given that the FF internals are larger than crop internals due to sensor size. So cramming an FF rig into that tiny setup would look unbelievably sexy (read: RX1R like) but would have underwhelming performance.
