I'm happy to hear of this since I have fond memories of DevNullMod (aka "Kitchen Sink Mod") from SEIV.
I would agree though with keeping the likes of the Multimedia Pack separate (not least since bundling an older version of MMP could cause problems with other MMP-reliant mods). If an installer is going to be used, then it could just check for the MMP and give a message (including a download URL) if it isn't found.
