Some ideas for Chapters:
Sons of Orar - Black fatigues, white shoulderpads and aquila, black weapons, and red armor.
Executioners - Black fatigues, camo armor, silver aquila, black weapons, red shoulder pad (Scout status).
Also, here is an alternative for Blood Angels, if the leaked Codex is right:
(5) Blood Angels Scouts
Syhn Avicen [Feel No Pain]
Heavy Bolter [Relentless]
Basic Scout [Preferred Enemy]
(Dedicated) Land Speeder Storm
They unit has Furious Charge and Fleet with Syhn, which is awesome. Comes to be the same price, too, but lacks the Cloaks and Power Fist of the other list.
