Yep. I built a lightning payment system where payments are cleared via a mint and settled via Lightning. If the payer and payee use the same mint, the clearing is done directly via the mint and does not even touch lightning.

What are the privacy implications of spending btc via ecash like Cashu?
Im early in my exploration but have extensive experience as a routing node operator.
Id imagine that in this scenario you are only as strong as your weakest link, which in this case is lightning. For example, spending of ecash across mints requires liquidity on lightning, and is only as private as we can assume lightning, limited by publicly created channel liquidity and potential man in the middle attacks whereby a well connected routing node may also function to surveil the network flows.
Can I assume the closest we get to perfect privacy with Cashu is when spending WITHIN the mint, where our anonymity set is infinite among other network users, and equal to the pool of participants using the mint, when viewed from the mint operator's perspective?
If these discussions are occurring or have occurred elsewhere Id appreciate any info.
