I kind of feel a bit bad for bringing this up as Ady has said the Battle of Hoth is finished. And I really don't want to come across as asking for anymore than has already been achieved no doubt. I am sure it will be amazing. But I have been looking into white loss from the original and the Special edition.
Now as small enhancements go this could perhaps be a way of putting back what has been lost color wise that is perhaps not possible to bring back through any means I am aware of. But I am talking about the white from the Flak Blasts only and any surrounding coloration which is faded in the Special edition.
These effects have been damaged although the picture has been enhanced although the cockpits have been over blown in some cases. Anyway I did a small demonstration of what I am trying to get at by restoring the whites. This does not pertain to any remnants of Flak Blast I am only talking about the white levels and aura coloration.
All Bar this shot I feel I managed to restore some of what has been lost in color whilst retaining the "new Look" of the special edition but keeping the white of the GOUT.
This seems to have been totally blown out this shot but the rest are not so bad that I have looked at. Anyway I did this in the form of a PDF as there are too many images to upload on a post so please see the PDF below.

Now weather this is something that perhaps could be considered an improvement or enhancement and something that you may consider doing to restore better white levels as I have omly used the hand drawn 2D animation from the Gout inserted over the washed out FLAK Bursts IN the Special Edition in there White State. Apart from the first one I altered the Hue and Saturation to match the original Flak Bursts rather than the new Special Edition ones.
Is it something that can be achieved another way or is this the only way? I think it makes an improvement but I will leave it there as I understand if it's now too late to do anything of this sort. Even if it won't take that long? although there are quite a few of them i think some are much more noticeable than others. But I think it improves and restores some of the original look and put's back some of what has been lost.
With something like this although very minor change throughout the film you start to notice it more and more compared with the original whites and the special edition whites and any color loss from their transfer and color changes.
EDIT
Playing with Hue and saturation on some of the original flashes also brings more color to the flashes which possibly is more enhancement to the original effects. In many of the SE flashes the color simply is not there to alter it.
On another note...
This may or may not prove useful as I came across this last week so I thought I better post it here in case it is helpful but not in terms of useable footage but perhaps movement.
