I'd be happy for them to lose Superjump given its current incarnation and gain something like 6-2 MOV. Keep them as the mobility option just change it up slightly.
I feel Rodoks are very good in Highly Classified and back up gunfighting. I think B5 HMG with mim - 3 is fairly respectable. Not to mention mobility to advance up the table and stay safe. Ability to end turn crouched in safety on top of rooftops is pretty powerful. I don't believe Onyx has access to such mobility outside the legates/umbras. Which have to fly solo and cost a lot more and are more fragile. I would really appreciate for more of their profiles to have mines as well, but alas, that's not the faction design. Mines are defensive.
