One change I would like to see would be having some Jedi wearing armor as in the Clone Wars series (not to tie in with the EU but to give some of the Jedi a medieval knight look) and also have some of the Jedi wearing pretty much the same outfit Luke wears in ROTJ (making that out to be an established uniform of some kind).
The idea that the Jedi wear moisture farmer robes all the time seems a bit odd.
I'm pretty sure I remember seeing concept art of battle weary Jedi at some point - things like Ki Adi wearing an eye patch, it was an interesting idea that they obviously decided not to go with.
EDIT: it seems they made an action figure based on this concept - see here:
