I know the leprechaun is a bit of a stretch, hence my "varying degrees" comment, but you have to remember that the forest men can come from a variety of backgrounds. Robin Hood himself was a noble who became a forest bandit. I imagine the leprechaun torso going on a real smooth-talker who helps smuggle things past checkpoints or distracts passing merchants while his buddies position for an ambush.
Anyway, a few more I didn't have time to mention earlier:CMF ElfCMF VikingKingdoms Scale MailHunchback from Vampire's Crypt
The Knights Kingdom one that Bigger Jim posted is also good, and I'll mix in brown, tan, or gray peasant torsos too.
