very nice.
Looks like the mics are mounted to the top of your camera...from experience, if your mics are cardioids you're probably gonna be able to hear the movement to the right and left as you pan your camera. It's been my experience that when I adjust my mics even a small amount, I can hear the soundstage image shift along with it, so you might want to somehow get the mics mounted directly to the tripod instead of the top of your camera.
I've done plenty of two cam recording on my own and it's an ambitious undertaking for sure! If you're closer to the stage, it can be manageable because you don't have to run as far because the two cameras aren't as far apart, but if you're back a ways and want to get a stage right and stage left vantage point, the cameras can be miles apart and you're running your ass off all night! LOL. It's worth it after the show is over, but during the show, you have to wonder! Ha! I think you have the best plan, to get someone else to man the second cam for you.
Also, hope you have plenty of spare batteries and/or power options.
Good luck!
