The changes that will protect ND are (1) merit-based playoff bids (likely meaning no committee); and (2) expansion. My understanding is that the SEC wants (2) more than the other leagues. You can't simply refuse to work with the SEC/Sankey, even though they played a big role in screwing us. Maybe he doesn't want to push for scrapping the committee. After all, Swarbrick helped develop this system and clearly failed to see how it could end up harming ND.
As things stand now, CFP bids are based partly on merit and partly on money. Not playing the bowl game has a financial impact, even if that wasn't the reason we declined the bid. It puts stakeholders on notice that we plan to fight back in terms they understand.
The big error he made in the media tour was acting like the main problem is the "process" because it gave the impression that ND was in and then suddenly kept ND out. The weekly show is silly, of course, but it was clear after the penultimate show that we had good odds of getting hosed. And seeing the shift in the rankings (especially OU and Bama jumping us for no good reason) exposed that the rankings themselves are not about merit. But the main problem was that ND was not fairly ranked in the final ranking, and under-ranked relative to the AP poll, Coaches' poll, FPI, S&P+, Sagarin, etc. We were the highest ranked 10-2 team in all of those rankings, but the fourth ranked 10-2 team in the committee rankings. He should have pointed that out. He could have done so without explicitly saying that either OU or Bama should have been out, even though that is the obvious implication. Maybe he didn't want to upset the SEC, idk.
