    well..yes ..why not.
    I just had a go at the disney vdb cloud asset
    ..and even with the half sized dataset..it renders too darn slow...at least compared to the primitive volume type, and it's a pain to tweak scattering and other channels.

    As a primitive, I suppose you can evaluate it with LWPrimitive,
    with the Item ID you get the LWPrimitiveEvaluatorID,
    its flag says if it is solid or gaz, then you have several volume functions,
    for ray marching through,
    I suppose also that bounds is what you need first for the renderer.

    Or knowing that OPenVDB is open source,
    make your own with a LWPrimitive handler.
