I have a solution for the third person guys. The stated point is that they want to see their big beutiful mech, so I think we can accomodate them, just like the arm lockers. Give two exterior views, one in front and one behind Center the mech and have the camera positioned to where it takes up about 70% of the screen, then give it about a 30 degree up angle to emphasise the scale of the mech.
I think this view mode would give both sides what they want. 3Per's can stare at their mechs, and the rest of us can kill them repeatedly.
