Add an extra volume pot to a 2 gain channel distortion box - questions...

[GeorgeSunset]

Hey, I'm trying to add an extra volume control to my overdrive (on for each gain channel – 2 gain channels)
The Circuit is much like a tube-screamer, so the switching between the gain pots is by switching between the output lug's of the pots (2x100k pot). It uses a DPDT switch (an LED turns on when switching on channel 2).
Could I just replace the switch with a 3PDT switch an switch between output lug's of the volume pots as well? Much like this (THANKS to "frequencycentral" for the diagram):



Should I double the ohms for both volume pots from the standard (5k std. would be 10k for 2 pots)?
Or doesn't it matter (just adding a 5k I parallel)? What would the result be? Less range?

Thanks for the help

(EDIT: fixing the picture)

Yes.

Use what you got handy. An "exact" answer needs more data, the usual problem is more distortion, but is sussposed to distort, so what's the problem?

thanks.

i ask, because i have to buy pots. have non around
