A Wien Bridge oscillator has two resistors or capacitors that must be closely matched.
I doubt you will find closely matched parts that are variable.

Millions have been built using stereo potentiometers, and they work perfectly fine - both commercially and as home projects.
My Wien bridge oscillator uses a
