Not worth it imo, especially since the normal texture doesn't look all that bad. I know when I seen close ups of Egil I wasn't thinking "Man, that eye texture overlay could certainly use an improvement". It looks good the way it is, and any improvements will be next to unnoticeable.
Edit: I also noticed things have slowed down in here a bit the past few days. Maybe that's a good sign meaning we've actually made enough progress that there isn't much left to do, in regards to the UI anyway. I can think of a few things but all of them are pretty minor and have no real impact (like that crown on the collectopedia screen, menu backgrounds, etc..). I think that finishing the maps and finding as many dumps as possible are the only real major things that remain.
