The driver surface area on an M22 is roughly the same as an M3, so any additional surface area would come from the sub and only be effective below the crossover freq. I expect there would be a difference in quality of sound, but not so much in terms of ability to play at higher volumes.

This is based on a lot of testing of M2 + sub vs M60, M3 and M40 at various times, not M22s, but for casual listening (where casual does not imply low quality) I ended up going with M40s and being very happy.
