That seems even more complex to me :lol
Assuming that you have a dedicated room, I would have chose a more Iron Man 1 method, with upper suit parts coming from the ceiling, much like a small crane, it would just hang and then start going down above you, and if you're standing still you would just have to let it slide on you like a t-shirt. That is for the torso and back part, and it would still need a way to secure them on you. I though of some crazy electronic strap tightener from the inside, that would pull the end of a strap like you would do on any regular fastex or strapping system, simply by rotating. The torso and back would be already linked by say, 2 straps on each side, but loose enough to allow you to slide in between, then once the crane would had lowered these two linked parts on your shoulders, the servo-controlled tightening of the straps would begin and seal it nicely on you. I'm still looking for the rest though ...
Just a few crazy thoughts in my too busy head, if it helps I'm glad, if not, just tell me to be quiet :behave :lol
I didn't realise he wanted to go that far, I though led eyes/reactors and motorized face plate and some other motorized gadgets were the goal, but I agree with you, if it has to have a fully functionnal heads-up display with A-R running on it, yes that will cost a hell of a lot more, more than a couple thousands I think !
