Sure, if magically you could have 4 conferences that are equal you could. But that will never happen.
I really don't see the advantage of the SEC and the B1G growing like that. They would have to break back out into divisions and then you would be back to where you were to start.
If the ACC breaks up, you have a handful of teams the B1G and the SEC would be interested in. But the marginal utility of each team you add is starting to diminish. Even FSU and Clemson to the B1G or the SEC has problems. And, at best, they can earn a share. But I don't see either of them driving revenue to make shares all that more valuable.
