I just think it's worth considering that in four re-appearances the only game to offer such functionality is the same game that had Luigi doing a Dark Hold drunken hobo dance. I don't see the Zero Suit as ever having a tactical function. It has only ever been presented as what Samus wears underneath the Power Suit; we could possibly assume it is an anchoring point for the Power Suit, but that's pretty much it. If Samus honestly intended to go into any suitless action, there's no reason she couldn't do so in casual dress (Zero Mission itself depicts such in one of its ending images). The Zero Suit, by itself, has no function.
