I'm not aware of any such efforts. What's the use case you have in mind?
from secp256k1-zkp.
Steganographic on-chain multisignatures using ECDSA, similar to MuSig applications (using ECDSA instead).

Can it be done without Pallier encryption? I'd be fine with Pallier in principle but my expectation is that any new heavy crypto would simply never get reviewed, and I don't want to waste some implementor's time.

I don't know, I have similar reservations about Paillier, though. Will need to think about it more, maybe something is possible with ECDSA adaptor signatures?

Will take a look at their impl again, briefly reviewed it before, and planned to use it as a reference for the Paillier stuff (since they got a third-party audit on their crypto).
