I don't think I've seen someone do it but I think it would make a great display. May I also suggest these glass shelves for your Besta since the Hot Toys figures would be light in weight.

If you ever decide to go with a light option, this will make it look classy . Plus, you won't have to purchase as many lights because the wooden shelves would be blocking the light.
I appreciate the tip. I was definitely looking at the glass shelves since I figured it would make them look nice.
