My first thought would be, "YES!" followed shortly by "Do I get to choose which animal?" and "Is death one of the possible side effects?", knowing me, I'd go for it as long as I get to choose which animal.
With a gene gun, some animal DNA and a few years of research, you could probably become your fursona, it would be hella expensive and painful I imagine though. Growing a tail could result in a very unhappy, or dead, person, not to mention the amount of gold you'd need for the 'bullets'.
