Yes, but some IRs are just bad in general. See my HRTF list

You'd have to add additional reverb components to support the surround image and that's a problem.

Mixing from the ground up one would think you could do any of the surround techniques you liked in a way that was compatible with the ambisonic system and folding down. Sounds good in theory anyway. The two camps need to come together.

There's still a lot of old school stuff going on in mixes too. Bass content like kick and bass guitar mixed to mono in either stereo or front L,R of surround to couple two speakers together for more punch. Keeping panning separation simple when possible with hard pans direct to speakers in stereo or surround. That might not just translate 1:1 to ambisonic techniques.
AFAIK I have not had to do anything specific (ie, reverb) for any system regarding psychoacoustics. Many HRIRs have reverb built in.

surround & ambisonics are 2 different techniques for sound reproduction, but the same psychoacoustics for human hearing apply to both.

It's even more important to apply "surround" techniques of hard panning to ambisonics because the spatial accuracy of ambisonics is even worse than surround.
