1. There is no way Kakashi could receive the Rinnegan. Kishimoto is clearly focusing on Naruto&Sasuke vs. Madara at this point. Madara will get his 2nd Rinnegan from Obito and will be defeated 10-12 chapters later. Giving Kakashi any sort of power-up would be ridiculous. My thoughts: He could become a teacher at the Academy after the war or lead a new Team of Genin.
2. The chances of Kakashi getting Obito's right sharingan is slim at best. I doubt that right eyes can be implanted on left eye sockets but Kishi could prove us wrong (after all in the Shippuden Series Danzo ordered Tenzo to steal Kakashi's left eye, which was the Sharingan and give it to Danzo so he could replace his right eye). Either way I would be disappointed. I feel like Kakashi played his role in the war just like all the rest of the filler characters. Even the Hokages are nowhere to be seen and Orochimaru is cleaning Sasuke's sandals atm.
