Are there any d20 stats out there for a were-weasel, ferret, or mongoose? or a race based on the weasel type ?

I'm thinking of setting up the possibility of a wizard/druid getting merged with his familiar/combanion via "transporter" accident resulting in either a blend or a shapeshifter.

Seems there are plenty of races/weres for frogs and ravens and horses (if the paladin falls in) and such, but not weasels.....
