Hmm, I could see that. If you could alter Mon Mothma’s line about “Many Bothans died to bring us this information”, it would be like she would be referring to that attack.
Although, we could assume Bothans wasn’t necessarily an alien race, but could be a term for humans, like Corellian, Alderaanian, etc.
Yes, in fact I can see it very well replacing the opening scene.
Here is a quick mock up:

With some more tweaking this could well work I think
