What is it your trying to say there. Do you mean send rinnegan instead of the sharingan. Anyway I've already considered that he wouldn't want to send Sasuke to Konoha or against Naruto because of how easily Sasuke is manipulated and that Naruto has been a major influence on Sasuke in the past.

However Sasuke already cut his ties with Naruto, and Hawk wouldn't even have to go to konoha because the reason Naruto and the others left the village in the first place was because they were trying to find Sasuke, so at the very least they could use Sasuke as bait to draw Naruto out because they know that no matter what he will come for Sasuke.
