An aerial bombardment/ground assault would have been designed to weaken the shields sufficiently enough for them to pass through without having to destroy what was inside. Having the AT-ATs and AT-STs come in with guns blazing would have been part of this strategy - pound the defense till it's too weak to defend, then you can do as you wish. You can liken it to Germany's aerial bombing of London...it was all designed to weaken the enemy to the point of no fightback (they just hadn't factored everything in!)
Or you could just say the Imperials got a little lost and had to rely on their GPS systems to get them back ontrack...!
There isn't a massive amount I would change in ESB. The Emperor's communication with Vader should be reverted to the original dialogue. It ties in too much to handhold the viewer all the way to Vader's reveal. Yoda should remain as he is...if anything, he should be replaced in the rest of the movies! Minor bits can be cleaned up and tweaked, but it doesn't require much. Irvin Kerschner's direction and detail is much stronger than the rest of the trilogy. But please make sure Luke doesn't scream going down the exhaust shaft - he made a conscious decision to fall, so wouldn't be screaming in terror. He would have been at peace with his decision.
