Custom piece design: Feature idea

Hi everyone,
As far as I'm aware, there is no possibility to add a custom piece design on lichess, which could be a real benefit for people who don't find what they are looking for in the available designs.
I am imagining a feature, where you can just upload .png or .svg images for each piece and then use it to display your board. Maybe you could even be able to share your themes with others, even though I'd imagine copyright could be a concern there.
Anyway, what do you think? Is this something other people would enjoy too?

You can use an extension such as Stylus or Stylish and then write a simple userstyle to change the board/pieces. Natively adding it doesn't sound bad, but I feel like it won't be used enough to make adding it worth it.
