How long does a fencing match last? A pair of AA alkaline cells will power an Atmega 328 with an nRF24 for several hours - like maybe 20 hours. Compared to the cost of fencing gear I suspect cheap alkaline cells are a trivial expense.
You would probably need to disable auto acknowledgements to prevent the two "receivers" from interfering with each other and that would likely make the system less reliable as the slaves could not be sure that their message was received.If the only purpose of this is to reduce the cost of batteries I don't see the point. Keep it simple.

You make some very good points. Thank you for the advice. This also fixes another problem. If all active strips have their master board constantly pulling data from the slave boards then any extra strip wanting to pick an empty channel can just walk through the channels till it finds one without traffic. Thank you so much. I appreciate it.
