They could almost certainly become just "angel-blooded" and "devil-blooded." Even if aasimar and tiefling are fully open (they're not listed as forbidden in the OGL or anything), it might be better to de-D&D-ize them as much as possible.
Yeah thats the kind of stuff I dont know/understand well enough.
I know they are in the 3.5 SRD, and thats why (I assume) they are in Pathfinder, and Pathfinder 2, via the Advanced Player's Guide, and 5e SRD (I think?), and therefore Level Up.
Just calling them Angel Blooded, or Heaven-Touched, or whatever, would be simple enough, but I guess thats why this whole dust up is such a mess.
