Abrams can't mess with Khan too much, since his reboot doesn't "start" until the destruction of the Kelvin. Anything before that should be the same as in the prime timeline, Khan included.
Which is why I agree with others that they should leave him alone, for now. I'd save him for the third or fourth movie when they actually have a good idea for how to use him and can get around or change his origin without making too much of a fuss.
