Hey guys I have this idea to convert an army for Chaos Marines(GW). I wanted to run it by you all and see what you think of it. Basically I was planning on using the standard Chaos Marine body for the troops and converting a Tryanid head to sit on it along with sculpting on a tail. Hopefully giving it a reptilian feel. The whole army is Chaos Undivided with the common theme based around the five-headed dragon Tiamat. Five man tactical squads and five total squads each painted to match one of Tiamats heads(Red,Blue,Black,Green, and White). Thoughts would be appreciated.
