As was previously suggested, you really need to sort out your flash misfires. Why not simply set up the lights at appropriate distances around the house similar to what you'll be using for the shoot and simply verify that you're getting reliability with the speedlights. You can do that without even using the camera. Simply set up the lights on stands and use the test button on the radio trigger to fire the key light and ensure that it in turn fires the background light. Start with fresh batteries all around. After you have reliability, put the trigger on the camera and take some shots. Shouldn't take long to get to the bottom of your problem.

Yes, I saw your earlier comments about having misfires using optical triggering, but the whole idea behind using optical triggering is to ensure that the trigger light and the optical slave are in direct line of sight. If folks are blocking the light, simply move the slave. In your upcoming school shoot, you're shooting one student or occasionally two. Put the slave on the same side of the student as the key light and it likely will fire every time.

Regarding those misfires of your background flash, I'd assume you're triggering that flash by radio signal. If it's the radio signal that's at fault, if you switch the flash to optical triggering, you likely eliminate the misfiring. Since you're shooting chest-up images, you can place the flash practically anywhere in direct line with the key light and get reliable flashes. Simply aim the flash body (where the optical receiver is located) toward the key light, while aiming the flash head itself toward the background.
You could do a similar optical trigger set-up for a fill light. I only mention this because you may find that you're constantly moving the reflector around, trying to match it's location to the various students (tall, short, in-between, girls, boys).
