Yes, to an extent, and this is frequently done to great effect. However frequency response isn't everything, there's also e.g. group delay, off axis response, and harmonic distortion. In particular, boosting response in areas a speaker is deficient often causes a huge increase in distortion, so you have to balance.

Yes, but no, but yes.

AutoEq (https://github.com/jaakkopasanen/AutoEq/) does something like this so... yes?

But targets various HRTF curves which aren't neutral or flat, and they usually aim for a Harman target of sorts, so no...

But there are some neutral-sounding curves that seek to just emulate pinna gain, so they have a ~3KHz peak which is required to 'emulate' the natural resonance of your ear, which you don't get naturally when you jam a driver all the way into it.

There's no AutoEq preset for the AS06s. Here's a representative sample targeting the 2019 Harman in-ear target for the KZ AS10s for funsies though: https://github.com/jaakkopasanen/AutoEq/tree/master/results/...
