I already thought about corusant before and there is just too many Audio dubs and new scenes with main characters so what ever I am not going to involve myself in the corusant idea any further basically I am not interested and do not care for the PT at all they were all pretty crap IMO and to go to so much work in order to make ROTJ fit more with the PT is not an option for me.

I agree completely. The reason I refer to this planet constantly as "the Imperial Capital" is to avoid associating it with the prequel planet Corsucant - though the two are very similar.

I'm interested in this idea more because I know it was once conceived of as a location in an early draft of Return of the Jedi, and I'd like to see this idea finally come to fruition after having been cancelled.

You can see Ralph McQuarrie's original concept art here, all created long before the prequels were even conceived of:

...and there's more where that came from.
