This! HT please take notes.
My only concern is part of the chest also needs to be swapped out between the sleeved and sleeveless versions, not sure if HT can engineer a solution. If HT were to only make 1 AoU Thor, I'm hoping it's the sleeveless. Valid point that they already have all the molds and tooling for both of the TDW Thor figures, just a simple paint swap and maybe a new base and they can go to market.
They could just leave a small bit of excess chainmail off the end of the arm, and then you just tuck it into the armor
