Question regarding Data

[Smashball2011]

What would happen if i didn't unlock everything in Brawl and decided to use hacks?

I ask this because I transfered my original Brawl Data to the Wii U, and I just need to be sure in case somthing goes wrong, and also cause I'm going back into Brawl Hacks.

Nothing bad should happen.
I run hacks on Wii U

My main concern would be CSS and Stage Selection hacks because some of them have their icons moved around, and I dunno what kind of effect it has on a person that doesn't have everything unlocked.
