jewels can take pretty good care of themselves but butti does get much, much bigger. So, you may be able to carry it off if you introduce the jewels first and let 'em settle down. Then you can add the butti. Rocky setup would take care of any subsequent aggression as the jewels will be able to hide where the butti can't reach.
Just a suggestion. Why not keep a pair of buttis only ?
Good luck. Keep us updated.
