Can I sell avatars in the Marketplace that exceed a certain polygon count?

Hi, Creators!

I would like to upload an avatar to the marketplace. However, the avatar has very distinctive arms and it is difficult to fit it into the documented polygon count.
If you know of a way to sell the avatar without the documented polygon count, please let me know.

Also, the official documentation states that transparent textures cannot be used for avatars, but is this actually impossible?

【Additional information】
・Some of the avatars provided by the official website exceed the polygon count (Image 2).

・The excess parts are arm parts, so it is assumed that accessories cannot be used in place of them.
・ Official Documents Character Specifications
