Modification Help with Idealian modification

I don't know if it's possible, but I want to modify my Idealian or SartoriaJ bjd butt area to detach from the doll and add strong magnets to it to stick 9 fox tails on his bottom. The tails would be like one big tail but branch out into 9 tails from the bottom tail. Does that make sense. You know like Idealian face plate, but instead like a butt plate. This sounds super strange now that I'm writing this. I realize my idea to add 9 tails by one magnet taped to the butt won't work, so this is the idea I came up with. Adding 9 individual tails would look weird I think. I wouldn't be able to do this myself I will have to hire someone, but is this idea possible? My idea is to have somehow an articulated jointed tail skeletal inner frame I found a similar idea design on etsy. I was surprised someone had the same tail idea as me. Then I wanted to make removable tail "skin" to go over that skeletal tail frame. Would this be possible? What sort of custom artist would do this. Is there a specific name for this service?

Would it help if I link the etsy page I found that had the similar idea to the skeletal tail frame I had in my head?

Also what is it called when I want to add magnets inserted into the back of Idealian instead of taping it. How would I do this. Would i need to drill holes into his back. I don't want to do this myself and risk doing damage to myself and my doll because I know I would mess it up and endanger my health with the resin dust by not being careful enough compared to someone more knowledgeable on this.

 

Thanks!
