A primitive for tokens that own tokens

Hello community

I hope this forum is the right place for these kinds of messages...

On my last project I wrote an implementation for the ERC1155 contract that tracks the owner of a different token on an ERC721 contract (tokens owning tokens). It's great for attaching memberships directory to SBTs while allowing to easily rotate keys.

I was wondering where and how might be a best way to share that with the community.
Since it's just a mod for an existing ERC I believe it won't qualify as a new ERC. I see may ERC variations are available here on OZ. Would you might be interested?
