Spanish isn't the same as Hispanic, and by the way, you aren't either.
I think if you take the ivys, UCLA, Cal, Stanford and Rice off the list, you have a realistic shot at the others. If you really do have Asperger's, write a banging essay on how you deal with its challenges and lead a problem free, accomplished life regardless. That will count for more than claiming some distant ancestry that you don't truly identify with, and can't even make seem believeable when they ask for your mother's maiden name.
And, they will.
