He would be an unregistered animagus, of course, like James and cia. What strikes me as odd is that most animagus turn into non-magical creatures (stag, dog, rat, etc) and turning into a phoenix looks unlikely.

Plus, because this does look unlikely: Fawkes had a burning day in 2year, in Dumbledore's Office, so that means Snape would need to have the life-spawn of a phoenix for enough time to become old, be re-born and grow up again so when he is transformed back into human he would have his original age? Ah... just saying it would make things really complicate.
