Does this smack of desperation or is it a sensible move to try and close the gap to Novak?
Personally not sure that re-igniting any past relationship actually works - Its driven on nostalgia and the dynamic of the relationship will never be the same as before simply because there was a before.
Here's an article from March of 2014 with an interesting comment:
in the days before the Australian Open in January, Murray compared the relationship(with Lendl) to a love affair that had lost its first flush of excitement. “I would try to impress my girlfriend a lot more the first few months I was with her than I do now,” he said. “It’s the same with Ivan.”

I think in hindsight Murray realizes that is the best he ever played. Whether they find the magic again is a good question. Back in the day, Djokovic looked intimidated by a Lendl coached Murray. I doubt that will be an issue now. He and Boris have been together going into their third year and winning everything.
