There's no key-binding change that works for this and doesn't ruin other weapons; there simply aren't enough (good) buttons on a controller for all the important functionality Warframe has. Alt-fire doesn't exist on most weapons, and many weapons with alt-fire have an alt-fire that is supplementary to the primary fire (which is to say, you don't use it nearly as often). So of all the functionality in Warframe, alt-fire draws the short-straw and gets the sub-par key binding because Melee, Jump, Use/Reload, Switch Weapons, Aim, Primary Fire, Crouch, and Use Power are simply more important in almost all play.
