Sure you can try, why not? Use your own head (wearing the in-ear microphones of course) for recording a live event, playback with HPEQ only (no PRIR or BRIR). Should be perfect (for yourself). Unless the microphones have limited fidelity (only picking up the test A16 signals is a less demanding job than doing a full range dynamic recording I guess, so it could be they are less suited for the latter). But as I said, just try. But you would have to sit/stand perfectly still during recording or otherwise you might get a bit seasick during playback! Or remember exactly how you moved ( ) during the recording and do the same ( ) during playback. Now maybe someone can figure something out to have headtracking as well. The trick of playing back through a crosstalk free PRIR that is sometimes used with generic binaural recordings, not made with your own head, is less suitable now. It would be a pitty to "add" an additional HRTF because this recording already has perfect HRTF for you applied to it, by your own head and ears. I am thinking of "constructing" a cross-talk free PRIR that does not apply the full HRTF for each lookanagle, but only the difference between your HRTF from straight in front and your HRTF for the other lookangle (and does not contain any reflexions/reverberations). (So looking straight forward it would do nothing, and looking 30 degrees left for example it would only apply the change in the HRTF.) I am just brainstorming here, I will think about it more.
