The idea is they need to be way more fantasy than scifi. Want a tech priest/most sphess muhreens? nope nope nope. Doomrider was allowed because he was the incarnation of the 70s, had a flaming motorbike and a skull for a head.
Fair enough. That also explains /tg/'s portrayal of him.
Melee space wolves, black templars, maybe a captain if he promises to lose some of his gear, I'd approve. Some of the primarchs actually have more likelihood of approval from me they were literally demigods and were either magical(Magnus the nerd, Mortarion's weird lamp+scythe combo), batman or loved their melee (Russ suplex! Angron too, Jaghatai to a certain extent).
What about Angry Marines?
And what kind of gear are we talking about? The Teleport homers? The Iron Halos? The Storm Shields? Give me some examples to work with.
Would I be restricted to specific types of Marines (Devastator, Assault, Tactical, Veteran, Dreadnought)?
Tyranid genestealers I'd approve in a heartbeat, but there is a no alien rule.
Sphess elves eeeeehhhhhhh there is a no alien rule.
Tau nope.
To the first, unfortunate, though that would get real awkward, real fast.
To the second, no offense, but fuck the Eldar. I am not risking giving Slannesh a little brother/sister.
To the third...I ain't about that life.
Kayoss cultists also approved in a heartbeat. 40k demons would be cool too, since they're demons and not aliens. (yes this makes sense)
Tempting. Eliphas the inheritor? Honsou? Fabius Bile?
Guardsmen would be case by case.
Okay, here are the cases I put before you.
Commissar Yarrick, Creed, and Inquisitorial aide Psyker Alicia Boone.
Necrons nope. Play terminator instead.
No problems here, though Trayzyn the Infinite might have been fun.
Orks I'd love to say yes but no aliens 
You dare deny me the chance to be Ghazgull Mag Thraka? Or Warboss Tuska the Daemonkilla?!
...Well, I'm going to have Old Man Henderson, unless Arch wants to do him again.
Squats would b
Squats?
One more thing. What about Imperial Assassins (Vindicaire, Eversor, Culexus, Callidus, and those other two that I can't remember right now)?
Not gonna ask about Custodes because they're kinda mini-primarchs.
