If the skins are the same res, and you know what .xml's to grab they could work. If you know what media files you need as well, and the names don't conflict with the ones in StreamedMP, then it WILL work.
This shouldn't be a problem. I was just unsure if the Plugin-xml's was somehow using some info from some other xml's. Like using .css when coding HTML, to be able to change the font type on all pages, with only one actual code-change.
I have no coding experience with XML's so I was unsure if this would work.
Now I am looking even more forward to this release! If I'm lucky, it will be waiting for me when I get home from work
