I'm not entirely sure what else they could other then dictating there be more States following either the Unit Rule or proportional allocation.
Unit Rule states could be rallied against by non-Ron Paul supporters as well, in my opinion, so they could end up hurting themselves ever so slightly.
I do see this election cycle as a blow to direct caucus states however. Maybe not so much in States where Paul supporters are at the helm, but in states where Romney and Santorum supporters feel they were robbed, leadership could easily rally the troops to make such a change an important issue.
