You can move the pots to where you want them without having to change any wiring. The neck of the pots are the same size, if I recall correctly. Just undo the nuts on the front, the pots will drop into the cavity, and move each control where you would like them to be and thread the nut back on. Perhaps label them before you do that, though 😉
The factory standard, courtesy of Breadbin, is
Upper front - volume, no indent, green
Lower front - pan, indented, blue
Upper rear - bass, indented, red
Lower rear - treble, indented, yellow
but, personally, I like to keep the EQ on the bottom, volume and blend on top. I'd do it like this
Upper front - volume
Upper rear - pan
Lower front - bass
Lower rear - treble
But it's up to you to decide. Put them where it makes sense to you.
