You don't need a network at all. Just email me who you want to transact with and I'll create a row for them.
The fact that I even have to ask you already demonstrates how shitty your third layer is compared to Lightning, not to mention all the other obvious ways in which it's infinitely worse.
In any case, seeing that I don't have a valid signed BTC transaction from you (because your 3rd layer suuucks), you don't want to allow free exchange between your layer and the upper layers, and I wouldn't want to bother with court litigation even if you were serious, well, have a nice day and good luck with your third layer lol
