Yes, any coin based off of Bitcoin Core 0.18 (which didn't make any strange Lightning-breaking changes) should support Lightning Network functionality. More good news: lnd has multi-chain abstraction set up and there are tutorials out there which you'd probably find useful as references.

Also, on a related note, Lightning Labs' blog post on Bitcoin ↔ Litecoin atomic swaps on Lightning is definitely worth a read.


See here for the code changes that were necessary to add Litecoin support to Zap. You could use this as a template for your own extensions to support whatever coin(s) you're interested in.
