I would do that if changing textures on planks was posible. Otherwise I would do everything on wood
You can change the textures to any texture the blocks have, this is done with the command console item woodplank 64 80 <---- this command = 64 x woodplanks with the texture id of 80. you need to do this in single player or be a admin on a server. most admins will do this for you or make some sort of deal with you to spawn this
