Certainly possible - although I suspect that a bit of additional circuitry would be required to drop the battery voltage to what's needed to power the radio and, of course, the circuitry from the rear battery would have to be modified to compensate for the voltage drop across the battery.
Of course, just keeping the Segway on AC power (with a timer to only apply the power for a few hours each day) would eliminate the "problem" without any modifications.

A second step that would improve the situation even more would be to add a low-voltage cutoff circuit on the path from the output of the two diodes to the radio board, so that a voltage of 60V or so would completely shut off the power to the radio board and reduce current draw to essentially zero. But this is more complicated to do, and might be unnecessary once the diodes are added and if you remember to check the charge level regularly.

IMO, very dangerous. Could result in turning off the power to the radio board while gliding. [And the same danger results from having a manual "on/off" switch.)
