Yes, that's the idea behind it.

We first need a good water model. I haven't modelled freezing in large
volumes (it's on my todo list), but purportedly the freezing point is
totally off-key. Whether this is an artefact of small volumes, or the
water model, and inasmuch this invalidates studied impact of
cryoprotectants I do not know (but intend to find out).

Virtual screening is very new, and requires a lot of resources, both
in terms of hardware and manpower.

Cryobiology is but a tiny subfied of a subfield, counting about 200
practitioners world-wide, most of them past their prime. Molecular
modelling is hence slow to enter the field.

Thanks to Greg Fahy, we seem to understand colligative cryoprotectant
mixes more or less well now.
