Well, if you want your snake to be susceptable to all the hassles they face in the bush then by all means compare them. So don't feed them when there is a shortage of food, throw in a few scars due eating live prey items, burn your enclosure down every now and then, don't supply any water to them when there is a drought. Making comparisons to the wild is a rediculous argument/statement.
I don't think a female spending an extra 2 months sitting coiled on her eggs and thermoregulating would be considered fun. It is stressful on her and is not needed. You are far better off removing the snake from the eggs and artificially incubating them. As for her and her eggs, as soon as they are gone and the enclosure cleaned, she will start smashing all the food that comes near so she can gain weight for the following season. Why add the extra stress to an animal if it is not needed. If you are doing for some trial and error work or interested in seeing how much extra weight she will loose due to being on the eggs for an extra couple of months then fine. But remember, these animals live in a captive environment where we control everything in the life, so lets make their life as less stressful as posible.
