I wouldn’t recommend moving in the direction you’re likely thinking. A single lightening node has no real built in concept of separation of power. Whoever holds the wallet keys has total control. Channels must be managed by an administrator who has total control over opening or closing channels.

In a group setting you might consider setting up an Alby Hub. That has a built in ability to creat “sub accounts”. It also removes the need for channel management and has a lot of built in integrations for nostr authentication etc. It’s also very easy to set up.

Beyond that i’d explore creating a Fedi Mint with a lightening instances. That would give you a governance structure for the bitcoin/feditokens while allowing you to use the lightning node for processing liquidity in or out of the mint.
