....so although the 'scaling' issues may have to slide, I reckon things would have tied better together if we could at least have seen the brief hint of an 'opposing leg-joint' coming in-and-out-and-in-again added during the approximate 5 seconds of 'prop' footage where Luke swipes upwards with his lightsaber....since the shot seems to show the AT-AT 'lurching forward' in motion slightly, and has matching sound effects already in place....
You'd really need to study the onscreen motion of this to see what I mean, but hopefully this gives a better explanation of how I think the existing footage could be tweaked -
....so in this first 'close-up' shot of the full-sized 'prop' when Luke's cable attaches, we would still continue to see a single 'leg-joint'....
....although when we immediately cut to the shot below showing Luke rising underneath ('Revisited' version - http://img139.imageshack.us/img139/1153/image1q.jpg), we can see that the AT-AT's 'leg-joints' are actually quite close to each other on the miniature....
....and when we then immediately cut back to the full-sized 'prop' shot below (which lasts approximately 5 seconds), it seems to have a slight 'lurching' movement that would allow for the subtle addition of a hint of an 'opposing leg-joint' coming into the LEFT of the frame a couple of times....without it having to overlap Luke's body in any way, or get in the way of his lightsaber swipe either -
....at the very start of the shot below, the frame doesn't move at this point....
....and still doesn't move at this point as Luke begins to twist around....
....but at this point in the shot below (when Luke has nearly twisted fully around), the frame begins to move slightly to the RIGHT (while the LEFT-hand side of the frame seems to go upwards too), and so an 'opposing leg-joint' could now start to enter the LEFT of the frame by the same amount (as shown by the direction of the arrow)....indicating the AT-AT 'lurching forward' again....
....the frame continues to move slightly more to the RIGHT at this point in the shot below, and the 'opposing leg-joint' would also continue to enter the frame slightly more too (as shown by the direction of the arrow)....
....the frame still continues to move slightly more to the RIGHT at this point in the shot below (as Luke starts to activate his lightsaber), and the 'opposing leg-joint' would also still continue to enter the frame slightly more too (as shown by the direction of the arrow)....
....the frame has now stopped moving to the RIGHT at this point in the shot below (during the lightsaber activating), and so the 'opposing leg-joint' would come no further into the shot either (as shown by the direction of the arrow).... The full hint of the added 'opposing leg-joint' would now be at the same position as in the shot above....as if to indicate a very momentary 'pause' in it's 'movement' ....
....but now the frame starts to slightly move back towards the LEFT at this point in the shot below (as Luke begins to swipe upwards), so the 'opposing leg-joint' would also start to slightly move back towards the LEFT by the same amount (as shown by the direction of the arrow)....
....the frame continues to slightly move back towards the LEFT at this point in the shot below, so the 'opposing leg-joint' would also continue to slightly move back towards the LEFT by the same amount (as shown by the direction of the arrow)....
....the frame continues to slightly move back towards the LEFT at this point in the shot below, so the 'opposing leg-joint' would also continue to slightly move back towards the LEFT edge of the frame by the same amount....and would now disappear offscreen again....before Luke then goes on to fully swipe upwards and eventually deactivate his lightsaber....
....after Luke's lightsaber has deactivated, and he has twisted around from us, the frame begins to move slightly to the RIGHT again at this point in the shot below....and so we would also see the 'opposing leg-joint' again begin to enter the LEFT of the frame by the same amount as before....as if to indicate the start of another 'lurch forward'....
....before we immediately cut to the 'close-up' shot below, which shows Luke throwing a grenade inside just before he drops down....
I have no idea if any of this is possible or not....or if you've already done something or other with it. But see what you think if not.
