With the amount of genetic variety that baseline humanity has? A Custodian, suitably disguised to hide the sense of transhuman awe, could probably pass for a variant of abhumans if they are careful enough.
Had a read of the Custodes Codex at my local GW last Saturday and the lore is looking fantastic, I plan to get it this Saturday at my stores birthday so i'll post some of my favourite bits there. But so far i'm loving the lore for the Aquilan Shield.
Aquilan Shield - Warhammer 40k - Lexicanum
These guys are like guardian angels in 40k, but a grimdark version of it because once you've fulfilled your purpose in the Emperor's vision, they don't give a f**k about you.
