Make a system named the Wii 2.
Put hardware in it like the PS4's AMD's APU design so games can be run @ 720p and 1080p easily.
Pack in a Wii Mote + Nunchuck and Wii U Pro controller. AKA get rid of the tablet, that design is for handhelds.
Buy Sega and Capcom (stop being lazy and...) crank out games, and hope for the best.
