It's great work doubleofive but there is a key problem with it.
Why do the fighters go in with the Falcon in the first place?
One obvious answer is the more ships that go in the more chances they have of success, in that case why ram or bam the reactor with the Falcon with a larger crew than the fighters?
The next obvious answer is to protect the Falcon on it's way in but that doesn't hold up because the Imperial fighters are traveling in the same direction as the Rebels (all the Rebel guns are pointing the wrong way).
If they are there to protect the Falcon the Rebels should split up and creep up behind the Imperials and pick them off or wait until the Imperials are in the tube and come in after them.
The best option I can think of (because we all want fighters in that maze with the Falcon) is that the Falcon is critically damaged in the bump that takes out the communications disk (as in my earlier post), it's going to blow up anyway so Lando sends Wedge out and rams the reactor, getting the best use of a failing resource.
