Custom graphics cannot co-exist in a level with default graphics, even with LunaLua as far as I'm aware. They must replace the defaults, but just so you're clear this can be done on a per-episode or per-level basis, you don't have to replace the graphics in the "graphics" folder in your SMBX directory. Just place the custom graphics you want to use in the level (with the filenames of the graphics you want to replace) in a folder or the same name as the level in the same directory as the level (in the episode folder alone for episode-wide custom graphics), and they will replace the default graphics in that level.
