Interesting links. Thanks for posting them.
The impulse response inversion technique has been done a few times. Comparing the old Perpetual Technologies SOCS method of just correcting the speaker and the Dirac Live room and speaker is interesting, the SOCS method corrected to a flat response for the speaker and the Dirac Live corrects to a sloping response for the speaker-room system. The latter is supposed to be the preferred in-room frequency response after room interactions. Of the two, I prefer the old SOCS method so far.
One thing about the Dirac Live method is that it does three measurements, left, right and both channels for the correction process. The mic can only be pointing in one direction for all measurements. If it would let you move the mic between measurements, you could try both correction methods and see which is preferred.
The good news is that Dirac Live uses the Dayton Audio UMM-6 USB calibrated mic I already have. Did not need to get another one, even though they recommend the UMIK-1 USB calibrated mic. One thing I found is not to use a USB2 hub with the mic. Had data stop a few times during the measurement process.
Will be interesting reading Floyd Toole's paper. Don Keele's CBT paper is interesting as well for line array acoustics.

Edit:
See that the DRC Designer is a free one that works with Foobar2000 with the convolver component. Will take a look at the process.
