I'm really hoping a 3rd party company comes out with a visor upgrade for Generations Arcee, either a visor or a full on upgraded head with a visor and G1 face apps for the face
I think you need to wait till people get Arcee. There are a lot of issues people are commenting on already. They may want other adjustments on areas they won't find till they have the figure in hand.
I think I'd rather see a third party make an entirely new back assembly for her first. It seems as though her entire alt mode is just a "shell" after all so it's probably not gonna be that crazy to say a 3p could make some new far nicer transforming parts for her to get rid of that turtle shell look she has going on. After that's accomplished sure it'd be nice to see a visor head, that'd be neat.
How bout a headmaster head while we are at it? Yes I know it's not feasible at this size but would be neat in concept form. As far as a visor head, if it was cheap enough maybe but I would leave that for someone like Tecrom on shapeways. He does extremely well with femmbot heads
I think we'll probably see a kit that does 2 G1 heads, one with visor and one without. Both with a slightly more G1 sculpt and paintapps than what Hasbro is giving us. Sort of like the Cygar kit for Generations Kup.
I plan on doing that if I decide to buy hasbro Arcee with paint... from 3rd parties I´d much rather they make a whole new mold for a WFC Arcee, which to me is the best design for Arcee with cool alt mode
