Nice idea, will it be successful? Probably not. So many forks these days and the zk-snarks method is not without it's faults. Also, it's not exactly future proof when it comes to quantum computing, there could be future risks if not resolved. We'll see how it plays out but I wouldn't hold my breath on this one. If nothing else, nice little kick back possibly for the ZClassic holders.
