@PTori30 Since they would need to get each artist who designed the masks approval and probably pay who knows how much. Then some of those masks probably have licensing on them the player/artist pays for. They had got Martin Brodeur's mask in the game because he was a cover athlete.
While it would be awesome to get them into the game I can't see it happening. Nor would I see a helmet creator where people could create those helmets coming to existence because of possible licensing.
