I don't think they should do this
They lose out so much cause they try to be so different
To a certain degree being different is good and doing and innovate stuff is even better but going against the norm in perfectly fine things is not.
Yes Nintendo doesn't have 3rd Party Support anyway but im pretty sure the "Fusion""NX" or whatever isn't made to be dead last place again.They want to battle for Top which is only possible with 3rd party support and such decisions would drive them even further away if this is possible at all.
What they need to do is establish some general things.
A Network which isn't worse than the one the Dreamcast had,go with PC-like architecture and go with Blu-Ray for physical medium.And if possible don't try to be special with weird gamepads that annoy developers.
Everything out of that is for them to go crazy and innovate.
