Wow, that's really neat! How many were redeemed (if any)? I think the chain method that I proposed is kinda harder for most people but it leaves an anonymous trace for you and doesn't require any server setup. Sweeping LN is easy but it needs a server/service to custody the funds and send them via LNURLw. Also, exchanging LN sats for fiat is currently harder than on-chain so these sats would feel less "real" for a stranger. After all, we're talking about fiat fans here and unless they can get their fiat quickly they wouldn't be interested in some imaginary numbers.
