nostr:npub1mhcr4j594hsrnen594d7700n2t03n8gdx83zhxzculk6sh9nhwlq7uc226 described an elegant solution to this: with cashu payment requests, the merchant itself specifies which mint the merchant is willing to accept.
At that point the wallet can do a swap between mints.
This actually makes accepting these things viable imo. If the merchant has a trust relation with a specific mint, and the ecash wallet has the ability to auto-swap, then it actually starts to make sense.

This still reads as if you expect to be receiving cashu tokens as payment. The receiver presents a ln invoice the sender, the sender "melts" their token and their mint pays the ln invoice to your mint of choice, which issues you cashu tokens.
You seem to be describing letting users pay you in raw cashu tokens from various mints. Users can send cashu tokens out of band or on nostr but lightning is the bridge between mints.
Cashu is better privacy custodian.
