Make replacable item match different charaters

Hello,

In my game, there is one female character and one male character. They have different meshes and bone positions. There are many replacable items in my game. Now I make two versions for each item, one for female and one for male. The male version is just a little bigger than the female version.

In this way, It will waste a lot of disk just for two version of items. (I have a lot of replacable items). Therefore, I tried to make a unisex version for each item. However, due to character have different meshes and bones. I can't make my item match my character perfectly. For example, the arm of my character is going through my gloves(a replacable item).

What I tried to do today was to upscale the size of gloves a little bit to match the arm. But I found that the scale of the gloves are totally controlled by the bones and the bones are controlled by animators. I can't change it from code in runtime.

I am wondering what is the normal way to achieve my goal?
