One of the benefits of doing editions like these is to bridge the gap between what may have been intended at the time and what is now possible to achieve, even on a small budget.
I don't think there was anything wrong with the intensions of the people making ESB (unlike the PT and ROTJ) so really all that's happening here is paying homage to the original material by giving it a little bit of a polish.
A bit of visable damage to the neck armour would be a good idea as far as I see it.
