I thought I answered this question during the Santa Fe meeting.
The answer is absolutely not. Particles follow a different mathematical model than molecules.

I'm CCing Michael who may be able to comment on whether a mixed HS/VHS collision model makes sense
for a solid/gas particle mixture.  It sounds like you are really asking for a mixture of 3 models in one simulation:
solid/solid, gas/gas/ and solid/gas.

If it does make sense, then we could think about how to implement it.

Is there a model for collision between a hard sphere and a variable hard sphere?
