Useless. LN is a payment protocol not a vault. Onchain wallets = your central/commercial bank LN wallets = your cash pockets

Use the 3 levels stash procedure for your bitcoins:

• HODL = large amount of your BTC, HW, cold wallets, your vault that you only deposit, your central bank
• CACHE = medium amount of BTC, your commercial bank, where you do coin control, cleanup, funds management (splits between HODL and SPEND), nodes liquidity
• SPEND = small amount of your BTC, enough for regular spending, your "cash pockets", LN wallets

I wrote a guide about this aspect here: https://darthcoin.substack.com/p/bitcoin-be-your-own-bank-think-like
