if the only thing that have sense to keep is bitcoin because of his monetary property, then the spending path could be:
bitcoin ---> atomico swap ----> txs -----> atomic swap ----> bitcoin
or, better
bitcoin ----> channel opening ----> lightning ----> txs -----> atomic swap in you want new utxos decorrelated -----> bitcoin
lightning is more efficient (1 atomic swap instead of 2). Lightning is the bitcoin tradeoff for spending, and dont add the risk of have a newly printed utility token with any economic sense.
