I kind of like this idea. They'd have to do something about the odd drone behavior, and find a way to make the drones assume the new formation in slowly, but it couldn't hurt much if they did. Could also make bombing runs a bit more interesting, tailoring your spread and formation to the target.
And of course, the most likely outcome is the same retarded divebombing we have now, with different formations, making it easier to divebomb a CV or hangars without any real effort or aim. That would be bad.
