Sure, people would be interested in seeing it but again, it has to be good to warrant 431, 310, and 380 million. Not to mention DVD sales for the Prequels.
I'm not saying the Star Wars name didn't help because obviously, it did. But, not to those numbers. The reason those numbers are so high is because of the new generation of children who caught on to Star Wars with this trilogy and not the Originals.
This is why the Star Wars films will always have a generational gap.....
