Well, here we go...
1) Just Dance games doesn't make any use of the enhanced Motion Plus sensing abilities. In fact, you can use older Wii Remote controllers without Motion Plus hassle free on any game of the franchise released for the Wii/Wii U.
2) Every game can interpret the sensor values whatever way their developers wanted. Just because it works with Just Dance (after all the app was made specifically for it) doesn't mean they will work with other games.
3) Although free, the app is closed source. The only way to see how it works would be by reverse engineering it, and even in that case I'm pretty sure we couldn't include that reverse engineered code in Dolphin without getting in serious legal issues with Ubisoft (not to mention this probably violates GPL as well).
4) A Wii Remote Plus (or a Wii Remote + Motion Plus accessory) provides at least 6 different motion axis, mapping them to a keyboard/mouse would be a nightmare (in fact, that old Motion Plus branch just proved that).
TL;DR forget Motion Plus emulation, at least with current hardware...
