Aasimar have a list of variant abilities and physical features, for which you would normally roll percent dice. My understanding is that you don't roll for anything PFS. If that's the case, is it possible to gain access to any of these variants?
As per the PFS Additional Resources page for Blood of Angels:
Other: variant aasimar abilities are not legal for Pathfinder Society;
The variant abilities you mentioned are not legal. The heritages (which replace the aasimar stat bonuses and some racial abilities) are legal, but the variants that normally require a percentile roll are not.
