These experiments have been done from time to time and have been reported
in the JAES; more recent work has equalized the reverberant sound field
as well as the direct arrival sound (a weighted optimization of the two...)

A recent paper is from someone at KEF, make what you will of that.

It's certainly well within the capability of off the shelf
DSP technology, and could probably make otherwise good but not
identical sounding speakers sound virtually the same if a good
LEDE listening room was used.  I'd try an experiment myself if
I had an audio workstation handy...
