Leaving aside the humdrum likes of Ney and Conrad Burns, I am of course hoping for DeLay, but also Hastert and, obviously, Norquist and Reed. In fact, bagging those last two would mean a lot more to me personally than some of those obscure members of Congress.
Karl Rove hasn't been much named in this setting. But he was close to other key players who are in trouble, and very plausibly (it seems to me) might have been involved in coordinating the matching of donors to desired legislative outcomes. So, assuming the prosecutors have the leeway, might a co-conspirator indictment be possible?
