Having thought about the idea of tying racial talents to tags some more, I think it runs into the same problem. I'd also forgotten that you can't change the tags of the origin characters which doesn't help things. So with the feedback so far I believe the best solution is to give the player options on their racial bonuses, which would require the most work from Larian. Almost as good would be what I suggested in the original post but I'm still unsure what to do with lizards and undead so it isn't ideal.
This thread isn't really about the racial abilities but I will chime in and agree with Naqel, it would be very cool and thematic and useful if Lizards could pick the type of their breath weapon attack.
