Audio Blending Between Opamps?

Hi everyone. Let me start off by saying that I am a hobbyist when it
comes to electronics so hopefully this question won't sound too
stupid. In a little audio project I am working on, I am using two
opamps (one dual opamp actually) as buffers for incoming audio
signals. I want to blend the output of the two opamps using a 100K
pot and then "feed" that blended signal into a third opamp. Will that
work like I am expecting or are there any concerns that I don't know
about?

I've seen circuits where the output of an opamp goes directly into the
input of another omamp (some bandpass filters for example) but is this
any different because the signals come together in a Y and there are
two paths for a signal to take? Because opamps have relatively high
input resistance (about 2M ohms typical in this case) and a low output
resistance (about 75 ohms), is it possible that the signal from one of
the "input opamps" will affect the other? Or is that never much of a
concern?
