It has been thought about in the past with the use of smart contracts on chain that basically have the private key for a coin and if you send a specific coin to it it can send the key to the new coin.
Just do a couple of searches for cross-chain transactions and you should get a bit of reading material.
At the end of the day, value comes from utility, fungibility and scarcity. So as long as those things are law in a crypto, it have value. Sometimes things happen like in ETH where the fungibility is destroyed.
