Maybe you mean will direct peer-to-peer Bitcoin to altcoins transactions be possible in the future?
This makes sense in case you think about decentralized exchanges, there are a few and you can trade your bitcoins for altcoins (and vice versa) there. Also, decentralized exchanges are present for ETH and for the tokens as well.
Maybe in the future the decentralized exchanges will spread but you should not forget about the lightning network and about the atomic swap too, so there are a lot of developments in progress to help bitcoin transactions in the future.
