Although, on a related note, IDW does acknowledge the difference in appearances in the MU story. At the beginning (set in the regular Abramsverse) Scotty and Dr McCoy are discussing alternate universes, they are shadowed by their Prime Universe counterparts, drawn in the likeness of Doohan and Kelley.
I take that as artistic license -- or simply as a bad idea. It's worth keeping in mind that the comics aren't canonical, and however much they may claim to be keeping the comics perfectly consistent with the films, they're a secondhand interpretation of what the filmmakers have in mind and they contain a number of discrepancies and mistakes. So what's in the comics is not authoritative.
