What problem will this solve ? ✅

Each class gets one appearance, but there is no way to personalize your look, reducing the feeling of ownership of one's summoners.

What is your solution 🔧

I suggest to integrate the rarity-skin open standard, managed by this contract : https://ftmscan.com/address/0xd1447fe5e70d58204946d61224643738ba54f5cc#code
It allows players to choose any NFT and assign them as avatars for their summoner. When no skin is assigned to a summoner, the current, default appearance is displayed. When the RaritySkinManager contract signals that a NFT is assigned to a summoner, the relevant image is fetched using ERC721's tokenURI() method.

Additional context 📝

I'm the developer of this standard, if you signal that you are interested, I offer to develop the solution and submit it to you through merge request.
