I'm planning to experiment with something like this:
1. Buy lighting from exchange, Relai or Pocket Bitcoin, weekly dollar cost averaging
2. Peg in to Liquid, using side deal, after each buy, keep in Green wallet
3. Keep it in Liquid up to a more significant amount, perhaps after 6 or 8 weekly buys
4. Peg out from liquid to on-chain cold wallet
What do you think?
That's what we created the Liquid swaps for 😁
Think this is the way forward for minimizing fees. Stack through LN, build stack on Liquid (using 2/2 multisig in Green), then peg out to base chain in a large UTXO.
Eventually these layer swaps will be built directly into wallets and won't require having to bounce around so much.
Blockstream Green has Bitcoin, Liquid, and Lightning (recently added, still experimental, need to be actived).

Similar to LN but you don't get instant payments with liquid. Also not many people/businesses accept it.
I like the idea of using liquid for smaller "change" on chain. For example if a phone costs 950k sats, I spend a 1m UTXO & peg out the 50k sat change.
Repeat and after many times you can consolidate & peg back into on chain.
I guess you could do the same with LN too
If buying from exchanges that don't offer Lighting withdrawals you can use Boltz for a swap (0.1% swap fee) or Sideswap's website to perform a peg-in (0.1% swap fee).

They also have an app if you prefer.
Depending on the amount it might take 2 or 102 confirmations. Check their FAQ for details.
Tdex is another app that let you peg-in (0.0%). It takes 102 confirmations.
If you use an exchange (Robosats, Relai coming soon) that do LN withdraws, you can use Boltz to swap into Liquid (0.25% swap fee).
For peg-out to Bitcoin, you can use Boltz (0.5% swap fee) or SideSwap website or app (0.1% pet-out fee).
