Personally, I might wait to spend a lot of time with him until he gets modded. If you would be interested, would you want his voice changed and pitched up?
Unless you REALLy know what you are doing this is what it would end up looking like:
All the companions are mocapped, which is probably while all are medium humanoids (ie human dimension). It looks like all the cinematics are designed around that. Maybe they've changed this for the release version?
