I think this has potential for reasonable adoption. It seems BCH users are more inclined to actually spend crypto than BTC users. They also seem more generally aware of on-chain privacy (based on their cashfusion use and apparently adding a version of stealth addresses soon), so perhaps there will be a large number of BCH users who understand they need the best private digital payments around.
As for actually implementing it, it's unclear to me whether lack of SegWit is a blocker.
