Mario Kart 9: World Tour

I thought the other day "are they going to make a Mario Kart 9?" I had an idea for a character roster, there's 56 Characters. Also I thought if there was this many characters in the game, then let's up the number of Racers in Races to 20. In Team Races- 2 Teams of 10 or 4 teams of 5.
=== Character Roster ===

Row 1- Mario, Luigi, Peach, Daisy, Rosalina, Pauline, Wario & Waluigi
