Is this feasible: Battle Royal, Winner takes loser’s Ethereum and NFTs.

Game world where people can battle each other and the winner gets to take the loser’s ETH. Once you accept battle, you can’t escape. So approving a transaction that gets put in a pool wallet first. ETH gets put into winners wallet after battle.

Or another method of players going in a wild area. They can attack others in this area and steal their NFTs if you kill them. If players health goes to zero than their NFTs fall to the ground. But I think NFTs all need an address owner. So maybe the person that actually made the kill gets their NFTs.
