I like the idea, but making it redundant because of timing would be unproductive.
We do need to try to settle on one candidate earlier, plus we need to strategize how to encourage as many RINO's as possible that they are presidential material and need to run.
I remember the primary debates as the most publicized period of all, the most valuable for voter educational purposes, but also divisive for the base, who had mostly already picked their favorite.
Somehow bookending the debates with regional events or rallies might lock in momentum for a nice chunk of time, going into the final curve of the calendar.
