Well, you might have to wait until Infinity comes out for an in situ editor, or one that can handle sprites, but this nifty little tool should help immensely in the meantime. It allows you to extract wall textures from M2 Shapes files, and save them in M1 format. You can then edit them with any of the Marathon 1 Shapes editors, and then reinsert them. The Marathon Shapes Juggler allows the transfer of shapes collections to and from Shapes files, the ability to store them in Shapes suitcases, and to create Shuttles for easy installing. Distributing shapes patches in shuttle format allows for far easier and more reliable instalation than Anvil patch files.
