I've made my own edit (just for my own enjoyment) of RotS and I find that removing the birth of the twins completely works pretty well.

My edit ends by showing the end of the lightsaber duels, Yoda saying he needs to go into exile, Kenobi returning to the ship and comforting Padme, Palpatine discovering crispy Anakin, Bail Organa telling Antilles to wipe Threepio's memory, the construction of Vader, and then the final shot is of Palpatine and Vader overlooking construction of the Death Star. Padme does not die (afterall, she is supposed to live long enough to raise Leia).

In fact, I have editted the PT in its entirety to hide the name Skywalker (Anakin is simply called by his first name), and Padme's pregnancy from the audience. So, when the SW movies are watched in chronological order, all the surprises of the OT are retained. The audience will not have enough information upon initial viewing to make the link between Anakin and Luke/Leia (until ESB/RotJ). It just goes to show that it CAN be done.

Although I don't know what Q2 has planned for his PT edits, I'm sure they will be much more professional than my amateur attempt.
