I just had an idea to make bloodseeker in TF2, and heavy for be was the best choice. Also, my friend, Deity Link made the blades already, you can find them on http://www.gamebanana.com/tf2/skins/116489.
It includes Team Color, as well as Jiggleboned Feathers. You can either replace Ellis Cap or Big Chief (since big chief somehow resembles the hat)
Made from scrap, especially texture.
