If not, why? I for one (and I probably stand for many people when I say this) would like to see the ability to possess multiple sets of arms, wings, and/or multiple sets of legs (centaur) without the requirement of poorly-made, non-animated prims or heavy scripting. My recommendation is to allow users to upload custom skeletal points to attach to the rest of the avatar, such as attaching a lower body to the pelvis, and to modify the existing skeleton (such as to create digitigrade legs)
