I'd rather see the Jedi have a last stand at the Jedi Temple on Coruscant, like the Alamo. Just massive amount of Clone Troopers fighting to get inside. When they finally breach as Megatron once said, "Let the slaughter begin!" Yoda gives the evacuation order and it's every Jedi for themself. As everyone tries to flee, Mace, and a few others decide to delay the Clone Troopers to allow some Jedi the chance to flee. Then Obi-Wan with baby Luke and Yoda talk together for one brief moment at their respective ships before taking off, never to reunite until The Empire Strikes Back.
(just my vision of what I would like to see happen)
