That is EXACTLY what I wanted to do ... and I LOVE your ideas...

Could you emerge Yavin IV with Endor? After all, they are both forest planets

You could swap Endor with Alderaan and Yavin with Endor.

It would mean removing the Falcon but here goes.

Dooku and the seperatists were the beginning of the rebel alliance.

They give the founders of the Alliance the plans.

The rebels try to defend Alderaan against the uncomplete Death Star but fall into a trap and get caught between it and the Imperial fleet.

They take massive losses and Alderaan is destroyed.

They retreat to their rebel base to plan a second attack.

Studying the plans they find a weakness in the station.

The Imperials track them to their base in the polar regions of Endoth.

They launch a ground assault apparantly driving them off the planet but this is a ruse to lure the completed station into the system to pick off their fleet.

The Rebels leave a small group of fighters which attacks the station's weak spot ( a large vent which leads the main generator ).

Luke doesn't blow up a Death Star (he's too busy confronting the Emperor and his father).

But he does take part in the defence of Endoth and goes off to face Vader.
