that would be vary vary bad, i feel that algos should be claymore dual miner resistant. just look at what happened to lbry,sia,pascal,decred every time this dude adds another the coin's price FALLS and falls real hard. Not only does it become impossible to mine and it will be a loss if anyone choose to mine at a loss. After he added pascal i sold all of my coins and fast then buy at new super low and never mine it again cuz the diff will be sky high! 
not to worry, the tribus algo is not dual-mineable as it uses generally equal amounts of memory and core which will detract from the hash rate of ETH/ZEC etc.
tribus algo is quite nifty as it uses very little power to do it's work as well, much less than daggerhash or equihash.
