Maybe I'm not understanding you, certainly not the part about exporting only the alignment data, which I don't think you can do. SKS is a tool for creating new & modifying existing WB (and other) skins. Is "flyakites mod" a WindowBlinds Skin? If it is, then you can "open" it in SkinStudio and the Preview should display the graphic elements correctly. If a WB skin is actually missing graphics, SkinStudio will substitute the default XP images from the Template file & display those in the Preview. If it is not a WindowBlinds Skin, then it depends - some other formats can be converted to WB format using SkinStudio (though usually not perfectly, requiring some manual touchup I understand) but that's something I have no experience with so I can't give you reliable advice there.
Again, I may not be understanding what you are trying to achieve, so forgive me if that's the case.
