This is reasonable in regard to high-functioning Aspies, but remember that ASD covers a wide range. I think it would be better to retain the separate label for Asperger's, because it is distinguished by normal or better intelligence and language ability (while sharing other traits with classic autism) -- however, even within the Asperger's category there is a wide range.
Another aspect that is often underappreciated is that the HF aspie, if smart enough, can learn to adjust to normal society to such a degree that he/she can often pass for normal, so that a diagnostician would place him/her at a different point on the spectrum at different stages of life.
