common5.pac editing

[Xace]

Is there a way to change where the CSPs are in a common5.pac? I recently downloaded a CSP & CBP pack that has some textures that I already have, but a couple of textures are on a different costume (ex: a Mr.L CSP is on the Fire Luigi costume) and then there are some CSPs that I don't need at all.

As said by all, use CUPASH to extract them. Also, the newest version of Smashbox supports CSP's.
Segtendo out.
