No.
When I want to play with Android, I buy an Android device.
To the OP, if you could install iOS on a Note 4 or Nexus 6, would you?
I dislike Samsung devices mostly because of Touch Wiz the Nexus 6 is way too big in my opinion, but on my Nexus 5 I would like to try it out.
I would have also like to have tried iOS on my HTC M7 which I don't have no more, sold it to get the iP5s when it was released.
