Replacing WWE logo in arenas?

[Starrcade_24]

Is there a way to get into the texture files of arena walls and replace the WWE logo or even retexture those walls to maybe a warehouse window, flags etc? I really have some great ideas and want to contribute as much as I can to create an old school NWA heritage project for old school and indy fans.

I found the arena ads in pac/arena/advertisement and can extract them with a pac editor but I'm having trouble getting them into the game. I did find a sort of work around for getting rid of the wwe logo banners on the walls though.  In create an arena, start with one of the arena templates, I'm not sure which one but one of them is a small arena with plain dark grungy walls.
