There is already a bitcoin version in equihash. Its called BitcoinZ dunno how people missed this during the hype.
Yeah its not a direct copy of the real bitcoin chain, but someone has already tried this with equihash.
Dunno but Roger seems to think BitCash is something special for jumping so high in the CMC charts and if this can dethrone that then ill be more than happy and even happier if it can dethrone B2X it has already peaked above the current B2X futures so its entirely possible
