Seth Meyers might also be an interesting choice because, like Fey, he's been a head writer on the show and also hosted Weekend Update and also knows most every aspect of the business side of things from his time at Late Night - but like several other former cast that were mentioned in the article, returning to SNL would also mean walking away from his own show, so he'd need to have incentive(s) to do so.
It'll be interesting to see how it plays out. SNL is Lorne's brainchild and during the few years when he left, the show tanked before he came back and assumed the reins again. Also, while SNL has obviously done something right as it's been around for nearly 50 years, at the same time, aside from election season and a few viral sketches here and there, it's not been terribly memorable for a while. Though MAD TV and In Living Color haven't been with us in years, many agree the sketches on those shows overall were sometimes better, more creative and genuinely funnier than SNL.
