I can imagine Alexander Sidding or Erick Avari as Doran.
As for Rufus Sewell... the only role I would find his appearance tolerable on the show is Ramsay. That man just gives me the creeps...
As for ethnicity, Doran is Dornish, not arabian, not spanish, not moroccan, not indian, or anything else. However, Spanish/North African is the closest we can get, and Arabian is pretty damn similar.
I must confess, I like the way you specify that Doran is not Indian, then suggest Avari (an Indian actor) for the part. Good skills.
Edit: Sewell as Ramsay? we obvious have very different ideas of ages; surely Ramsay is a young man mid-20s or so?
ReEdit: Rheon is 27, and Ramsay certainly has to be believable as McElhatton's child; not convinced he could have a kid in his mid 40s
