Yes, absolutely. The transaction costs on these higher levels should be very small. I’m expecting the zaps to flow freely.
For example, most people send zaps on nostr with primal which is a custodial lightning wallet. Being custodial, like a federation, keeps fees low.
It’s a tradeoff and sovereignty has a cost. Federations and custodial solutions like Primal are cheap but you give up some sovereignty because you don’t hold your own keys.
