Make the ballrace ball morph milestone use upgrades

so currently, upgrades are out and you can customise your ball and such.
my idea is to make it so the ballrace ball morph milestone uses these upgrades instead of being a default ball
so instead of just seeing this

it looks like this but in the plaza and condo when you use it


just a interesting little idea, or maybe you can work it into its own milestones like 1,500,000 exp you get more customisation on the ballrace ball morph, so the ordinary 800,000 exp is still the same

definitely for this
