To put it simply, Fusion Anvils need to be able to work in the same fashion as FriendStory outfits where you can use it on an item that isn't gender locked, and it will lock the gender to male/female. As it stands, most, if not all, end game items are gender neutral, leaving many outfits unavailable for use with the current anvil system. Adopting the already implemented system from FriendStory would allow more options for fashion, which benefits everyone.
So as it stands, you can't fuse a gender-specific item's appearance onto an item thats gender neutral such as every piece of end game gear. It'd be great to see this changed similar to how Friendstory's school uniform works on gender-neutral items.
