No, it doesn't. He lacks EMS, he lacks Uchiha Blood, or Dna. Susano'o is even rare when one has Uchiha DNA. He pops in two eyes and goes PS instantly? If this isn't poor writing, then I don't know what is. He could barely mainntain one Ms, but now he's rocking two MS. Oh boy, this manga has sunk so low. So low that it's no longer funny.
The best thing would have been to give the forever-crippled-without-Sharingan Kakashi back one of the MSs' and the job would have been done. This is much bigger than Minato's SM hindquarters pull, I kid you not.
Well, Kishimoto sure proved one thing - Kakashi is nothing with Uchiha leftovers. Congratulations Kishimoto, for finally making that clear to everyone.
