@finland they've confirmed that "both your look and your attribute bonuses/maluses as an Angel will depend on the family (sub-race) of your character. Same for Beastmen -> Abominations. Other unique abilities of the original sub-race (e.g. night bonuses for a Shadow Demon) might persist after the transformation too 
" which means that at least some of the traits will be changed depending on sub-race. I'm just throwing this out as an idea for Blood Demons when they become angels.
