Voltage switch for Paragon

I like the idea of being able to switch between 9v and 18v on the Paragon. It seems to me that this could be achieved with a simple DPDT switch mod, with diodes D7 and D15 being removed from the board and soldered to the switch instead, thereby isolating the TC1044 from the rest of the circuit.

For 9v, the switch would bypass the TC1044 and connect the +9v supply directly to the D15 cathode pad on the board (through D15 soldered directly to the switch's output).

For 18v, the switch would connect the +9v supply to the TC1044 via the D7 cathode pad on the board (through D7 soldered directly to the switch). The output from the TC1044 would then be connected from D14 back to the switch and finally to the D15 cathode pad on the board (again, through D15 soldered directly to the switch's output).

Does this seem feasible? Is there anything I might be missing here?

Thanks
