Yes it's possible, it's not entirely impossible. If I recall successfully Cardano was hardforked into Account model from their UTXO model in 2021. So opposite would also be possibel. It's a huge pain to shift, so more often well stablished don't do such things.

At least for Bitcoin, moving to account model is probably impossible without breaking few things. For example, certain output (such as P2MS and P2PK) doesn't have address. If such output assigned to address by hashing the scriptpubkey and convert it to certain address format, i expect it would change exact script required to spend it.

You probably recall it incorrectly, since cardano website claim Cardano use extended UTXO.

Cardano uses the Extended UTXO (EUTXO) model to support multi-assets and smart contracts while maintaining UTXO's core advantages over account-based blockchains.

Extended UTXO and Account model is nearly similar. So that is why I mentioned it as a account model. Since they are supporting smart contract and smart contract is account model.

For a blockchain like Bitcoin it would be too drastic and unnecessary of a change that you would never have enough consensus to implement this change. Hard forks are extremely rare on Bitcoin and the account model has worse privacy because you use the same address for all transactions.

Also, Bitcoin isn’t trying to be a clone of Ethereum, so I don’t see any benefits to doing this. Similarly, I don’t see any major account based chains switching to Bitcoin’s model due to the impracticality of such a decision.

It might only be feasible on a zombie chain, where it would be easier to have users migrate to a completely redesigned network. It would be similar to how Binance had their original Binance Chain and everything gradually transitioned over to Binance Smart Chain.
