If I can soft-fork in anything, it would be something far more effective than MW :)

MW is really a scaling tech that has some privacy advantages (primarily due to ephemerality).

Monero-like privacy that you can easily opt into.

This is 100% possible, and quite scalable today (and I even have a friend contemplating opening a technical BIP on how to achieve it). This would 100% replace the need for Monero etc. and would have massive improvements to upper layers like Lightning as well, which could benefit from the improved on-chain privacy.
