I hope we get much promised decred soon (suprnova is getting too big with 27k miners), lbry credits would be nice too (claymore gave nice boost for it).
And of course i think easy adds would be zencash (equihash), ubiq (ethash) and bytecoin (cryptonight).
Now would be a very good time to add DCR and LBC. Yiimp went down and will be for some time (He got hacked and will not fix it until after his vacation, if ever), so those miners will be looking for a place to mine.
