It would be really fun if tweak custom match settings to make unique experiences, like enabling special modes or even tweak things, for example you could tweak: character speed, gravity amount, win conditions (like last to be hit by a red star wins or last survivor wins), wind or no wind and the frequency of it, amount of rounds, player amount, lvl1 or lvl5 skills only, random skills, etc.
It would also be nice for content creation and hosting events

There are all these cool modes so it's a shame that you have to wait weeks just to be able to play them again only within specific timeframes
And custom matches have so much untapped potential that's only limited by it's own design
