Miyamoto should be kept far, far away from any management position. He'd be worse than Iwata.
Look, the guy is a great game designer, but there's a reason you wouldn't want your interior decorator to be doing your dental work.
Business is business.
Miyamoto would be even more Japan-centric than Iwata most likely and absorbed into his own ideas of what game development should be, and he's made some questionable decisions in the past.
Such as pushing Nintendo to use cartridges over CDs on the N64 because he wanted fast load times -- great for his games, but it cost Nintendo basically all their third party support and handed the console market to Sony.
He looked at Dinosaur Planet and forced Rare to turn that into a Star Fox game. He's also said he'll never make a violent game because he insists all his games (and presumably all EAD games) are playable by his family. Which is kind of an insane business policy.
Don't get me wrong -- great designer. He's earned the right to make whatever game he wants without question or interference. But 100% the wrong choice to run a business.
Nintendo needs someone younger and understanding of the Western market and marketing in general to offset Iwata. Nintendo's management is typically a bunch of old Japanese suits who are stubborn, slow moving, and out of touch. Bring in a Western person who knows the market and can counterbalance that.
