One thing i thought would be cool was a hybrid pack i drew years ago: Basic design: power cell of the movie pack on the left, three light cyclotron of RGB pack, gauge and crank generator in the normal place side by side, RGB gun tip and barrel that extends/retracts via lever, move forward grip design but brownish grip color like RGB, twists like movie, gun main box, movie overall design but small yellow light up rocker switch like RGB in place of two silver toggles like movie gun, small red light on right of vent light slightly yellow, trigger box combination movie and RGB, coloring mixed with movie coloring overall pack and gun, rear grip, same as movie, brown RGB color. Trap can be belt mounted or pack mounted, provisions for both, ALICE pack . I was 13 when i drew it, 40 now. I thought it was cool.
