Just thinking out loud...what's to keep the scrypt asics mining CSC? They are looking (for the most part) to get ROI and will mine whatever coin does this the fastest. Not sure if relying on next gen scrypt asics to secure the blockchain will work. If anything they make it much easier to do harm than good.
It wont work, 93% of current hash power is merge mining, so the last stat I saw anyway.. that leaves little left to go around and even less to secure the blockchain,.. AUXPOW seems to be where all the hash is headed and I don't think it would hurt the security selling point of CSC, Not sure how it would effect price....
