In the era of film photography, dry ice (frozen CO2) was used as coolant for film (it was placed behind the film in a special container).
So the idea of non-peltier cooling is not new, nor it is implausible.

Simply try it and report results..
However, peltier cooling may still be much more practical, compared to other methods.
