sc_selcharacter.pac too small?

[MrDarthGogeta1]

Well this is a fine pickle I've gotten myself into.

After getting BrawlEX to work on the Project M Launcher, I was trying to lower the filesize of sc_selcharacter.pac due to having slots for custom cosmetics for clones. It was doing good for a while until I hit 3263 KB on my file. When I tried to load up the CSS, it froze before it even got to the menu for it. Is it really because the filesize is too small?
