Here's an idea for a solution: If you have the vWii HBC (OHBC) and the HBC WiiVC inject (GamePad support) installed, maybe you can launch the WiiVC HBC using the GamePad, then going into the Wiimmfi disc patcher, and if you still have an original Mario Kart Wii disc, you can insert it into your Wii U and the app will temporarily patch the disc, and you can still use the GamePad as a Classic Controller, and you can play online via Wiimmfi. Any questions? I haven't tried that method out, but it's worth a shot!
EDIT: Just tried it a few minutes ago and it just kicks me back to HBC. So that's not going to work and it never will. So that means Mario Kart Wii with GamePad support cannot be played online via Wiimmfi.
