I would love to, and I did try, but you can't really get a 'frame' of the Loader lifting it's foot up to take a step -- obviously the thing would topple over. So instead it looks like it's shuffling toward you -- which isn't very exciting.
Not sure how comfortable you are in photoshop, but depending on how many frames you'd have to make it walk, you could always do a "green screen" trick and place something under the elevated foot to keep it standing, then use photoshop to remove it after.
