We dont have our own blender exporter yet, but we have seen various methods on how to export to an Ogre mesh format which is what Skyline uses. We will have a look for you but to help us could you do a search for "Blender export to Ogre mesh" and let us know how you get on.
We currently have no plans to export models from Skyline but we are looking into importing various formats such as fbx, obj.
