This is totally out of the box.
What I'm suggesting is to modify the firmware of two Yonguo products: YN600EX-RT Speedlight and YN-E3-RT Speedlight Transmitter.  Unlike their Canon equivalents, they have USB ports intended for upgrading their firmware.
These two products have a master/slave relationship with two-way RT radio communication.  The problem is that they're not sharing as much information as they could, like battery level.  How many times have you been shooting with multiple off-camera flashes when one of them dies due to dead batteries?  You can't tell because you still see the other flash firing.  What would be helpful is if the YN-E3-RT altered you that a flash went offline, maybe by blinking the link light, beeping, removing the bolt next to the row of that flash on the LCD screen.  And if you could send battery level, when it's low you could alternate between the bolt icon and battery level with an audible beep as a warning.
There are other limitations, or gaps, in the RT protocol that could be filled.  For example, the controller doesn't ping the slaves at all; if their status changes, the transmitter doesn't update its screen or link light.
I know it's not a DSLR, but Yonguo must be using the same processor that Canon is in their 600EX-RT and ST-E3-RT products.  It's a huge derivation from camera firmware, but think about it: of all the wireless flash triggers, none of them are programmable.
Notice the bolts on the right side of each row.  They could be replaced by battery level when low.  Same with the radio icon in the upper right (for the transmitter's battery level).
