Episode I would be very easy to do the theatrical cut of- the 5.1 from the LD is already on some type of bootleg and we have the establishing Coruscant shot from the LD. And the official DVD with the "Watto cheering shot" on Disc 2. It would just be a matter of putting it together.
Episode II: Still sounds like the missing footage has not surfaced in high enough quality to be mixed in with the DVD. Which is too bad.
