Yes, its:
25% Winning Percentage + 50% Opponent's Winning Percentage (OWP) + 25% Opponents' Opponent's Winning Percentage (OOWP), where home wins & away losses count 0.6, away wins and home losses count 1.4, and neutral court wins and losses count 1.
Games already counted are omitted at the next step away, so in conference game AGAINST the team are left out in the OWP, so the average opponent's winning percentage IN MAC PLAY will always be .500. Differences from .500 in OWP brought into the conference by MAC schools will be based on what out of conference wins the MAC school brought to the table.
Note that AFAIU, parity scheduling directly affects RPI if it results in stronger schools rotating home and away series against weaker schools in different years, it doesn't directly affect RPI if all schools still play each other. So long as all schools all play each other, parity scheduling is about building a more attractive resume for schools whose RPI puts them on the bubble. Since the MAC is not there (an optimistic would add "yet"), that form of parity schedule is just a hypothetical notion.
But a top six and bottom six where each school in the two divisions each played three home and away series against three schools in the other division would affect RPI directly, so long as inter-division games went to form, by boosting OWP in MAC conference play above .500, and by boosting the OOWP through "filtering out" three of the six weaker schools from the six stronger schools. If the OWP of the other members of the "first" division was also stronger on average than the three "second" division schools they skipped played, it would also increase the average OOWP.
That structure obviously allows a rivalry game to be protected despite the rivals ending up in different divisions, but at the possible cost of every once in a while a pair of teams end up not playing each other in two consecutive years.
As far as movement between the divisions, you could go for fair, or you could go for drama. Maximum drama would be to have the top four in the first division seeded into the MAC tournament in Cleveland, and the six in next year's first division being the six that played in the two quarterfinals and two semi-finals in Cleveland.
