How bad could Star War Empire beat the Rebal if they spend equipment soldiers best equipment possible.

First move been the last is simple way put if all tie fighter shields all likelihood shoot down all Rebel fighters or at least Vader shoot down Luke skywalker. Han,Luke and rest of the team would wipe out stromtroopers when the fighter start since Stormtrooper armor provide some real protect against blasters.  So movie been hour long with Empire have the death star plans.
