How about Weremonkeys? Monkeys are awesome, they have climb 30', high dexterity, and opposable thumbs.
Werehorse? Werebat (or vampire as we like to call them)? Wereowl? Wererhino? Werewasp? Werespider? Werescorpion? Weremantis?
Many of those were probably said before. I was serious about that Weremonkey thing, monkeys are awesome.
EDIT: That template template idea is awesome.
