9v to 18v On A Switch?

[Chuck]

I’m having some unholy thoughts about modifications to a Tube Screaming Ultra build. I’ve seen some pedals with a switch to toggle between 9v and 18v – which excites my inner teenager.  Digging through my stuff I have a Roadrage board that has been configured to take 9v in and spit out 18v (don’t recall what I intended to use it for – but it was supposed to be epic!).  Would it be feasible to run wires from the center lugs of DPDT stomp switch to the 9v/Ground on the TSU board, take 9v/Ground from the GPCB 3PDT board to one side of the DPDT to provide normal 9v/Ground to the TSU, and also take 9v/Ground from the 3PDT to the Roadrage then to the other side of the DPDT to provide 18v for the glorious transformation of the TSU into the Next Big Thing?

If all the grounds involved are common, there is no need to switch the ground wires and a SPDT On-On toggle would do fine.

And whether SPDT or DPDT, anticipate a “pop” when switching the voltage.
