Tim Ruffing, Elliott Jin, and I are working on a MuSig2 BIP that we would like to propose to the community for discussion. The BIP is compatible with BIP340 public keys and signatures. It supports tweaking, which allows deriving BIP32 child keys from aggregate keys and creating BIP341 Taproot outputs with key and script paths. You can find the BIP draft at: https://github.com/jonasnick/bips/blob/musig2/bip-musig2.mediawiki
The draft is in a state where it should be possible to write an implementation based on the BIP that passes the basic test vectors (as, e.g., demonstrated by [0]). The draft BIP also contains a reference implementation in python. Please be aware that this is only a draft and that it may still be necessary to make small tweaks to the algorithms and test vectors.
