Starting up a new, DIY Chapter. What I have so far is a very heavy Greco-Roman theme. Just to clarify, I don't consider the ultrasmurfs to have a Roman theme any more than any vanilla chapter, there isn't enough of it to be what I would call a theme.
I already have bits from Blood Angels Sanguinary Guard and will be getting Minotaur things, amongst other bits. I already have Sevrin Loth and his Honor Guard, which I also plan on having in this army. The name and Chapter Emblem is where I'm hitting a snag, while I will have bits from Blood Angels, Minotaurs, Red Scorpions and just some random non-GW here and there, their Parent Chapter I want to remain a mystery. I like the iconography of the Scorpions and Minotaurs, and one thought I had was to have both. Go with either or Constellation theme or just some of the more well known Mythological creatures. Scorpio for the Honor Guard, the Minotaur for Termies, etc.
Would using different emblems like that, but still using either color or a background to link them, to designate squads or roles vary too much?
