Combining 2 different types of clownfish in one tank

[Coralgurl]

Would it be possible to mix clown species in 1 tank? I've got 2 black and whites and 2 clarkiis, I'd like to add the b&w to my 180 as I'm shutting down the 55 gl tank. The other fish in the 55 should be fine to add in (flame hawk fish, 2 chromis and a flame angel).
