[Stage Help] A 2.5 version of Chemical Plant Zone

[Rage83]

I've made a version of Mewtwo2000's 3.0 version(version of a version xD ) of Chemical Plant Zone. I MAY have gotten the filesize down low enough, but at this price:

(ignore the white boxy thing. it's just Brawlbox showing a poly that's hidden in-game for the original Chemical Zones. I have the higher-res textures still. I want to know if it's at all possible to lower the filesize enough to have the stage run with the larger textures. Have a link to it: https://www.dropbox.com/s/zwm32iee0qw2y0e/STGCUSTOM20.pac

Goes over Green Hill Zone without an REL.
