Since the warframe is based one multiple warframes being put together from the old war. Why not have it where the player gets to select 4 warframe abilities from other existing warframes? You could have wukongs clone walk around with excaliburs exalted sword. Or Gausses speed mixed with volts ability to crowd control. It would allow for many different combinations of this frame and not just one set version. Allowing even more playability and a lot more content for people to discover.
