Looks like you're "it". Congrats (or commisserations)!
One suggestion is perhaps trying a thematic approach to a Round. Sort of like combining the MSA approach to the "pass the camera".
I know that in both rounds I've participated in - by the time I got the camera I felt so pressured to pass it along - that I spent virtually no time thinking about what to shoot.
If you pick a "theme" ahead of time - then each of us can think about what we'll shoot while waiting for our "turn" behind the lens.
