If I understand you correctly, you are saying that both opportunistic suspend and dynamic power control should be used together, with dynamic power control being used for short non-busy periods (as in between keystrokes) and opportunistic suspend being used for longer non-busy periods (as in while grabbing a coffee). That combination of usage sounds promising to me. That said, I don't know that anyone has really sat down and thought through how one might apply suspend blockers to a desktop system. I suspect that there are several ways to go about it.
