I suppose it is possible...the same possibilities as JKR
retrospectively casting Dumbledore as being gay, or her suggesting Hermione could possibly be black. It's a bit too stereotypical for me. I am not sure that I approve of every single introvert/outcast being stuck in the ASD box, because many AS do not subscribe to that particular image. Still, he does come through well at the end, but whether he makes an unlikely hero for the AS community, remains to be seen.
