I would think so, but only at R: Personal. The problem would then be that the MuVi spell to let you use it on someone else would be just as hard to develop in other Arts and might well end up being a ritual itself.
The toughest one in my mind is if it applies to your own longevity ritual. Is that a transformation? Considering it can work by "by directly affecting the tissues of the magus’s body," it would seem this is self-transformation, so long as only done on yourself.
It should. We usually abbreviate that as mMF, though, to distinguish between mMF (minor) and MMF (major).
