Protools offers these pan centre options :

-2.5dB, -3dB, -4.5dB and -6dB

-2.5 was their original value, possibly copied from Neve
-3dB for constant power
-6dB for constant gain
-4.5dB for compromise between constant power and constant gain, also used
on SSL mixers.

I think this proves that whatever law one chooses, it won't keep everyone
happy.  There might be some mileage in taking the Serge type equal power
circuit, but making  the pan CV attenuation adjustable after the lin-log
converter - that might allow the law to be smoothly varied (never tried it
- I could be talking bo££ocks).

I've never heard of any console or DAW pan EQing the sound to simulate
greater distance.

One of the aims of the Buchla Lopass gate was that it should have "the
capability of simulating the spectral and amplitude changes that accompany
a receding sound source", so panning using something similar might be
interesting.  Amount of reverberation can have some impact on the
impression of distance too.
