Active Audio Blend for Stereo Signal from single dual gang pot
Yes, what you show will blend the two input signals, with the blend portions dependent on the pot position.

However:

R17 and R20 are pointless.  I can't even guess what you think they accomplish.

The TL074 is a FET amp, so Vcc and Vee don't make much sense for power pin names.

Showing negative power at top and positive power at bottom is obnoxious, especially when you are asking others to look at your schematic as a favor.

The power pins seem to be shown twice for U9, at U9B n U9D.  Even more confusing, they are connected to something at U9D, but seem to be left open at U9B.

There are no bypass caps anywhere.

The actual power voltages are not shown.
