A little lost in the sauce of class + archetype mixing...and feel like the idea i had in mind gotta be aproached a little differently

So in short, had in mind making a (titan) nagaji with mixing monk and inventor so i can spec into the pantograph gauntlet with potentially use the innovations to make it really pop, issue is...dont know if monk would be too fitting for the "punch monkey" character i had in mind (essentially idea being he uses an exo-rig esque build buuut, any other ideas guys?)
