I would be concerned with that seaping through the shell into the egg. I’ve heard of using mineral oil, but same deal. I wonder how something like just olive oil would work.
I assume most preppers know that eggs do not need to be refridgerated, though they last longer that way. You can tell if an egg has gone bad if it floats in water.

I hate spelling errors.
Well, it’s not necessary true that the egg is bad if it floats. I have had eggs that floated that weren’t bad.....my test is that if they smell OK and the yolk doesn’t collapse like water, I use them. Never had a problem.
My understanding is fresh eggs, straight from the nest and unwashed, keep fine at room temp. We try to eat our birds’ eggs within 2 weeks, and have never had a bad one.
For off grid, or intermittent power, we concentrate on items that need no refrigeration. Canned, dried, individual serving sized items, etc.
There was a time folks used “root cellars” for cooler temps (not 40 degrees cool, though) and running ,ountain streams with cooler boxes placed in them to keep items cool.
With enough preplanning, ice can be made in the winter and stored a long time in underground, heavily insulated areas, an ice house. Works better the further north you are, of course.
On your fridge, you might try stepping up the size a touch or adding 2 to 4” of Styrofoam insulation to all surfaces except the heat exchanger coils, do not forget the door, insulate it too.
I have a small, backup fridge that is about 3’ tall X 2’ wide. It is very energy efficient, and cools very well.
I was taught that fresh eggs do not need refrigerated for several days if the storage temperature is not warm. We kept eggs on the screen porch, not in the kitchen. We just wiped off the fresh eggs when we gathered them and my mother washed them right before use.
Modern store eggs are washed before they leave the farm which washes off the protective coating the shells have so they do need to be refrigerated.
“I would be concerned with that seaping through the shell into the egg.”
Not an issue. This is the way our grandparents preserved eggs. It basically deposits a layer of glass on the shell that seals all the pores.
Mineral oil will not go rancid.
Unwashed eggs last longer than washed eggs.
