There are a couple of images that unless the code is rewritten are dependant on a few images in the fusion.apk. All the ones you see floating around are ones that fern and I modded on firmware 2.08. They have the fusion/skin dependencies written out and are independent in the mms.apk itself. I think it would work on 2.17 but I don't know if there are any changes. I can dig one up for you to try. But again, it's an older mms.apk.
If you think you can do the mod to the mms.apk I'll let you know exactly what images you need to edit in fusion/skin.
