AoS Warcry warband composition

[Dracorex]

I just got the warcry starter set, and I was wondering: What’s stopping me (matched play rules wise) from making my entire warband just rocktusk prowlers (the lion creatures) with maybe the occasional beastspeaker (the one with the whip). Or an iron golems warband with just ogres. This is (mostly) hypothetical, so ignoring all of the obvious financial and tactical impracticalities, is possible to do it in principle?

Every warband needs a Leader. Other than that, knock yourself out.

Thanks. I was thinking of using blue stuff, but I wanted the the Rocktusk Prowler to feel more special, so I decided against it. I also had an idea of using blue stuff on the Raptoryx bodies and using them for cold one conversions, and using the frills for Salamander conversions.
