DSP to increase perceived distance between speakers

[musictechwriter]

We downsized to a much smaller home and our music listening area is less than ideal. There's no way to create an equilateral triangle with the L and R speakers and our couch. The speakers are too close to each other. It would be great if the built-in DSP could include a way to increase the apparent distance between the speakers where you could input the distance between the speakers, distance from that center point to the seating area, and the WiiM Pro would automagically adjust EQ, delay, or what have you. Thanks!

I guess to describe this more generally, a stereo expander effect is what I would like to request, but one that tries to compensate for speakers that are too close together vs. the old type of expanders that just created some out of phase sounds. Thanks.
