Having Psycho Mk-IV's backpack here is really cool. Not only does it enable fun ideas by sticking it onto other suits (I wonder how BUNNyS plays with Psycho Plates?) but gives Mk-IV itself more depth. There's room for alternative loadout options that don't rely on very experimental new Psycommu tech, or going for a different style of a NT unit and for example mounting Hazel booster pod + Hrududu II and a Gigantic Arms unit. It should work very well with them.
Not to mention we know G-Doors is Unit 3 of the Mk-IV line, and there's at least two others that are likely to have different loadouts too. This helps imagine what could be different about them, since the backpack is easily replacable. As a bonus it also connects to how the beam rifle is some kind of offshoot or refined version of the standard Mk-II rifle which was talked about at length already.
