The problem with Peltiers for this particular application is not so much being able to drive them, but that you're essentially putting a hefty heater inside your fridge, whihc is obviously not designed to be treated such.
I don't know whether this is feasible, but you might want to consider retrofitting a mini fridge with cooling elements from a large-scale freezer, so you'll have enough cooling capacity for the Peltier freezer inside the mini fridge.
