Will Yanukovich return?

It would seem to me that if Russia is intending to install its own government in Ukraine then the man they would choose to lead it would ideally be Viktor Yanucovich. Viktor Yanukovich is the democratically elected leader of Ukraine who was ousted in a coup in 2014. He has been living in Russia ever since. If he is the man that they put in charge of whatever is left of Ukraine at the end of this war, then it would allow the Russians to undercut all of the criticisms that have been leveled at them in terms of an 'unprovoked attack'. If they can claim that they are restoring a democratically elected leader then it would certainly give their invasion legitimacy in many eyes.
The greatest problem with this strategy, however, may well be Viktor Yanukovich himself, I have no knowledge of whether he would agree to be re-installed as President of the Ukraine. Particularly, if it is over a partitioned Ukraine. I believe he has previously spoken of trying to get Russia to return The Crimea, so he may not be willing to go along with what may be Putin's current plans for the Ukraine.
Further evidence that the re-installation of Yanukovich is unlikely is the fact that we have not heard Russia saying that this is what it is doing. This might, however, be because they wanted to keep their real intentions unknown to this point, or it could be that Putin is waiting to see how well his invasion goes before choosing his end goal and he is not yet sure that he will choose the one in which Yanukovich would be helpful.
