We could throw "Angelic" in there as a sort of Half-Angel race.

Yes, that would be neat.

Ok, Dragonborn, Tiefling are out.
Lets go with Half-Dragon, Half-Demon. A version of Dark Elf from the Giants adventure, and possibly some other races.

Actually, I was trying to say that Dragonborn and Tiefling are Open Content under both 3e and 5e, only that we should not be trying to closely emulate 5e's version due to 5e's OGL does not really lend itself to allowing content for export to other systems.
3e is a better base to begin with and it should be OK in a close emulation (though I still prefer the all original route).

While on the idea, how about this for BFRPG version:

Tainted (Tiefling or demon/devil heritage)
Touched (Aasimar or goodly planar being heritage)

Ok. We can still switch the names. I'd like to see other people's interpretation of these races too. Thanks.
