How about Miller, Martens and Frattin on the 3rd line. All skate pretty well and if Miller is going to give you anything offensively, that combo might work. Then you have Zajac, Malone and Radke to take care of things physically on the 4th line. Agree that Trupp injury hurts, but Genoway's is brutal for this team at this time of year if he is out for an extended period of time.
Addendum: Got back from ATL last night and when I watch yesterday's game, Genoway's hit looked like a shoulder issue as he was coming off the ice?
