Any ideas on how to import League skeleton files (skl), and export skn files from Blender?

I've never made a custom skin before, and the old Blender plugin is broken and outdated. I was an idiot and made a shitty model of Mettaton EX and a low poly (E) bomb (if I could import that too,) for a Jhin custom skin. I know there's resources for Maya, but I'm a pleb and don't have a small loan of a million dollars to drop on it (and there's no way I'm pirating it). Any ideas, cause I'm seriously out of help, and need it.

Here's the model I guess. (I didn't lie when I said it was shit.) http://media.lolusercontent.com/api/embedly/1/image/resize?url=http%3A%2F%2Fimgur.com%2FCBWKPob.png&key=a45e967db0914c7fb472fd4381e6c85b&width=425

And here's a Less shit Captive Audience bomb. http://media.lolusercontent.com/api/embedly/1/image/resize?url=http%3A%2F%2Fimgur.com%2FnSI0XdS.png&key=a45e967db0914c7fb472fd4381e6c85b&width=425

So yeah, hit me up with any idea's cause I'm really outta luck over here.
