Would they add final form mahito

I’ve always been a mahito main and a huge fan of him and I’ve always thought that because he does other things in the anime like black flash and use his final form they should add it,I just think that they should add this due to how little he does in the game compared to the anime. I don’t know if there is any confirmation on this but I really think they shouldn’t keep him as an NPC, same for the other ones like Dagon.
