I think this would work best focusing on either a heavy/assault unit or on a more maneuverable striker style unit. So Thugs, Highlanders, Atlases paired with Alacorns, Manticores, and Pumas with heavy weapon team infantry or go with Quickdraws, Wolverines, Phoenix Hawks, Griffins basically faster jump capable mechs, jump or regular infantry in Cobra transport VTOLs, and Lightnings, Condors, and Cyranos for the armor component. Trying to mix heavy and fast together just gets the unit spread out and unable to support itself. It'd work a lot like a RCT or LRCT but just need to keep it focused on the TOE.
