Not a bad idea.

I'd say we can start with a bad model and see if we get any interesting
results from it. Someone can then test results in the lab.

I don't disagree, though finding even better cryoprotectants should not be
overlooked. Plus, you've set new problems to be solved, which can, I
believe, be solved against the space of cryoprotectants using GA. That is,
cryoprotectants which flush well.
