Let me see... obscure monster PCs from the past that could be resurrected:
Svirfneblin, Wemic, Flind, Swanmay, Aleax, Verbeeg, Norker, Vegepygmy, Skulk, Meazel, Tabaxi, Xvart, Nymph, Dryad (Hama- optional), Manes, Margoyle, Ghoul, Wolfwere, Pseudo-Dragon, Salamander, Satyr, Centaur, Vampyre, Myconid, Formian, Foxwoman, Selkie, Araena, Dakon.
If I've gotten a few of those wrong, please excuse the spelling.
I've played a Satyr Paladin (thank-you Reincarnation) that was just plain weird. Not sure I'd do that again. I've seen a Centaur played back in Temple of Elemental Evil, that was a pain; simply not built for stairs and low ceilings.
It occurs to me that you could re-tool the -weres for use as PCs (maybe create the different forms as stance utility powers?) rather than Lycanthropes (to eliminte the 'I bite everyone in the party!' problem). I'd be interested in Vampyres as a non-undead alternative to the whole vampire thing.
Tabaxi (cat-people) could be a good addition depending on the way you do it. Gotta make them cool to compete. Dakon I'd want just so I could DM a talking ape wizard.
