In my opinion home world aptitudes do not work. See here for reasonings http://community.fantasyflightgames.com/index.php?/topic/114226-psi-power-re-reqs/
What I will be doing is removing the stat aptitude you get from your Home World and give each PC a stat aptitude pick of their choice. So if you want to be a perceptive feral or a tough noble you can.
Thank you cps and Fgdsfg for helping me to arrive at this conclusion
