Well those must be in 100% or im going to hate MK 6
The side modes must be:

1.Time Attack
2.Survivel
3.Practice mode (MK 4 style) but expanded alot
4.Tournament (2 on 2, 8 player TOUR. and BIG 16 player TOUR. with Dragon King's lost treasures in the endo for the winner as a prise
5.Endurance
6.I cant make another one perhaps you can add your idea
ALSO i want to be able to fight everibody in ARCADE MODE i mean there must be towers like MK 3 and one of them must be like MK 2 style were you can play against all the charecters including jade lol.Thats aLL for the moment
