Personally I don't play wormwood in DST, but I do like his old design and I hate seeing interesting content go to waste, so that's why I ask for his old development art to become a skin in DST, it would both be an interesting skin and save time because most of it is already finished.
Klei had most likely even planned for this version of Wormwood to enter DST because this sprite sheet has the sprite for the bonesaw emote from said game. To be frank though they had scrapped this version of Wormwood because they didn't like it so the chances of my suggestion coming to fruition are low, which is fair.
