Elcor, Human, Asari, Turian, Krogan, Batarian, Rachni are the only Reaperifyible. Salarians have short livespans, making them useless, Drell are too underpopulated and it would take too much time to convert them to some sort of shock trooper. Yahg are too aggressive, Quarians immune systems are too weak, Geth are synthetic, Hanar... are jellyfishes, you could probably use them as projectiles and so on. Elcor would be formidable, could be used as living tanks or transport (if transformed correctly).
