I saw a reading of this with Marcia Gay Harden as Laura Bush a few months ago as part of an evening of Kushner one acts dubbed "Tiny Kushner" at the Schimmel Center at Pace. Kushner greeted the audience and then afterwards, Jeffrey Wright performed "East Coast Ode To Howard Jarvis" (a monologue), Ben Schenkman and Linda Emond performed a fascinating and very funny one act play called "Terminating, or Sonnett LXXV." Then, a VERY pregnant Harden did the opening scene of "Only We Who Guard The Mystery Shall Be Unhappy" (I remember reading this scene in The Nation about two years ago) in which Laura Bush reads the "The Brother Karamazov" to a group of dead Iraqi children, who speak in only bird noises. Rita Wolf co-starred as the Angel (Wolf was featured in Kushner's "Homebody/Kabul"). Harden was wonderful (and absolutely nailed a Texas accent) -- when Kushner finishes the full work, Harden HAS to play Laura. A very interesting and entertaining piece.
Mitchell and Clarkson should do fine with it. FYI -- it's not a full evening work at this point. I'd guess that it runs no more than 40 minutes or so (I suppose the roundtable will help fill out the evening).
