Converting elec stove to gas?

Anyone have a ballpark idea of whether this is even feasible? I live out on ten acres, and everything in the house is electric. The oven/stove is old and I am thinking about replacing it, but would prefer to put in a propane gas oven. That way, if (when) the power goes out, while I am waiting for the electric company to remember I'm out here, I can still cook. I've got a wood stove, but it was definitely built for show and not function. Would it be cheaper to convert the oven or just rip out the wood stove and put a "real" one in?
