Not sure how you could do that without revealing amounts to the 2nd mint because they'll know the amount they receive in lightning from the 1st mint (and know it's from the 1st mint since they're redeeming it's token), and the 1st mint will know the amount they're sending to the 2nd mint even if they're not colluding.

And it still wouldn't solve the reduced anon set from "larger bucket" ecash holders unless you spread funds around like you said or never send/receive larger payments.Still better anonymity and privacy than Bitcoin, but coming back to my original point...ecash doesn't necessarily have a larger group to hide in just because it is ecash.

I was kind of surprised the other day to find out that mints can tie IP addresses to specific tokens (maybe that should've been obvious), so I like what Mutiny is doing with Harbor running everything behind Tor 

 Yes, the second mint would know how much they’re receiving but not how much you have in total. 

The first mint would know how much they’re sending but wouldn’t know who’s sending it. 

Sounds like tor is crucial for this to stay private and also important to transact in relatively small amounts. 

I thought this was helpful:
