Need to run that experiment on the ISS in a Mars-gravity centrifuge. Despite a lifetime of 6-9 years, though, their generation length is only a few months; if they reproduce in that radiation environment for a year or three and there aren't serious mutations, they'll probably be okay in the long run.
