Binaural surround methods for protools with headphones

[Ale]

Hi all

I am currently investigating possibilities to record and process sound
to make surround sound on a simple stereo headphones

I do now tests with several dummy heads.
I have found the plug in from wavearts helpful to get surround
Panning for behind upper and lower work quite well so far.

My main problem is to get sound from the front


Are there any other ideas for recording mixing binaural content
