Looking over the list of files given in the downloads, there's a problematic few that do more bad that good when removed:
Certain "Adventure" stages actually contain the boss fight data required in other modes, including the Master Hand battle at the end of Classic mode. Removing these stages therefore cause problems for Boss Battles and Classic mode.
Removing every movie file instead of just the ones explicitly tied to Subspace seems like overkill.
General courtesy, probably should keep the brstms so that people could use them for custom stage music.
This is everything I see as an issue.
If possible, I would also like to see if you can remove the Subspace button from the menu in order to prevent the game from crashing.
