I think the arms should be less senshi and more mecha.

So ToQ Arms would be Red Ressha.

Kyoryu Arms would be Gabutyra.

Buster Arms = Gorisaki

Gokai Arms = GoJyuRex. Or GoJyuJin.

I think it would be fun if they kept their original Arms color though. So Gaim could use Build Ressha. Baron would still be Gabutyra. Ryugen could take on GekiWolf, and Zangetsu could be.....well, the only green that matches is Green Ressha.
