yes if you use thunderhub there is a swap out functionality using bolt.exchange or you can you use https://fixedfloat.com/. and send lnd payment to an invoice that is then swapped to your own btc on chain address then you can use your btc onchain funds to open a new channel

for example, open a 20M channel with breez, send 10M sats to fixedfloat swapping to onchain btc then open a new channel to WalletofSatoshi

this gives you 10M of inbound capacity from breez while maintaining 10M outbound from WalletofSatoshi and 10M outbound from breez
