Magic Realm transformation and Virtues from other Realms

A very simple question concerning Transformation in the Magic Realm (from RoP:M, p.26): can a character (without might) use vis to gain supernatural virtues/flaws fromarealmotherthanmagic* ? E.g. to gain Sense Holyness/Unholyness, or to exchange an existing flaw with a Faerie Antipathy? Technically, the book does not forbid it, even though it does go on at some length about what can be gained and what cannot. It would seem strange to me if the Magic Realm gave access to stuff of other Realms, though. Any thoughts?
