The funny thing is, had Lucas not sold his company, and he lives long enough to see technology advance enough, we would have had a remake eventually. I can see him now, rubbing his hands together eagerly, the day technology gets to the point where you can successfully replace actors with totally different people. Mark, Carrie, Harrison, and other cast members would be replaced with a better looking cast. Also, the dialogue would be changed to have characters shout "Nooo!" for the entire film. Eventually the entire thing would have been unrecognizable.
