Wi-Fi would never work on boards. People would just quit like crazy. Although, if you download the Project64k emulator for your PC you can play any Nintendo 64 game online, including Mario Party 1-3. I do this all the time for Mario Kart 64 :)
As for the entire idea overall I'd say there's no need for it. People who liked the old mini-games would probably prefer to play them on their old disc/cartridge.
