It's possible. A token contract can call another token contract to check a wallet's token balance and decide whether a transfer should succeed or fail based on that.

They just need to be on the same chain for it to be done at the contract level unless something else feeds that data into the chain such as an oracle

It’s like a 4. 

I can whip up a quick prototype if you would like!

it may get wild if it's multiple contracts for the nfts etc.  if your NFTs and your token would def be easier.

I don't have much experience writing contracts. Adding that functionality shouldn't be hard, if you're already familiar with the rest of the complexities of writing and deploying a contract.

I suspect that there are no-code tools that let you deploy a contract with this type of setup.
