Aha, so your concern is the blocktime, and not the fees itself? interesting.
is it doable? yes, you can port lightning to a lot of blockchain (ltc and doge included) but i dont know if the bch community has the same motivation as btc user to run a LN-BCH node. running nodes cost money and with fee incentive almost similar to zero, i doubt there is much interest
BCH developers and enthusiasts pitched it as a low-cost alternative to Bitcoin that could be used as cash (this was before Lightning was launched as a second layer response) and could scale on chain due to initially raising the blocksize to 8 MB (32 now).
It was always intended in its design, and its messaging ("we're the real Bitcoin, not Blockstream Coin™ (which is Liquid, and no one uses that LOL)!") to be a successor to what was presumed to be a dying cryptocurrency due to the hubris of so-called maxis who took "have fun staying poor" far too literally.
Just like there's barely any BitcoinUnlimited nodes left, I doubt there would be any dedicated BCH-LN nodes. It's why I muse about this functionality being designed on the base layer, because only BCH makes it feasible as a mainstream(-ish) cryptocurrency. The others are privacy coins.
thanks!
