If you want to play with different sized avatars then I'd probably learn the basics of fucking around with unity. Its fairly easy to take an already ready to upload avatar and change the size. You just change the scale, then also the viewpoint values by the same multiplier.

Most of the whacky sized avatars I've seen are just passed around through cloning. I think I've seen a giant anime girl avatar from the Kings Raid avatar world?
