I suspect you'd simply get a different book, written by someone "more Indian"
(just for fun, I'd pick a very alternate
Farrokh Bulsara, even if he's about ten years younger
than Said).
Said wouldn't have much reason to write the book and I'm not sure I see the reason that
he instead would write one complaining about the lack of attention.
On the other hand, the issues don't go away just because the focus lies elsewhere.
(I also can't help noticing that the painting you linked to portrays something
more stereotyped as Indian than Middle Eastern.)
