Extending OMM to AABB primitives

I’ve been working on a volumetric path tracer for a few months. I re-check Ada Lovelace arch whitepaper and I re-read OMM technology. In case I haven’t explained well what I’m talking about I drop this link:

I was wondering if this technology could have a sibiling for procedural primitives using 3D textures kinda hardware accelerated ray-march. That’d be cool. Maybe you guys are on that already. I hope to get some information that can be made public.
