Sure.
Tbh the less represented global biomes, animals-wise, right now are alpine and temperate forest. As you might guess from my name, I would love to see some goats species added (dall sheep is fine but clearly not enough). If done right (improved climbing and jumping animations, rocks-climbing needs, smaller hitboxes), goats could inspire people to build very intrincate rocky enclosures unlike what you'd build for any other animal.
