I'm not sure how somethign like that would work Robert without rediculous amounts of lag. I know Second Life has a limit on how many pieces can make up a drivable object for just that reason.
Personally I don't really want much. Maybe a secondary wood texture (or make it dyeable), a few more crops and growable flowers, gates for fences, coral, and maybe give the wolves a few more abilities and I'd call it good.
