Anybody extending Cashu so that my wallet doesn't share a Bolt11 invoice with the mint, but instead just shares a path computed by the wallet?

I don't want the mint to know what is being paid, but the Bolt11 invoice shares a lot of info with the mint

Bolt12 is kinda relevant, but I don't think there's any way for me to take someone else's Bolt11 and then convert it to a Bolt12 by adding my own blinded hops
