I expect that is a good idea. Long term Electric heat may be the best option based on availability and cost.
When we rebuilt our house I added 30 amp 220 volt outlets in four places. The 220 volt space heaters work very safely and are stored if not needed. It is not so cheap but it will heat the entire house. Actually one in the basement and one in the sunroom will make the entire house liveable temp wise.
If you will put the 220 outlets near an operating window you can put in a window unit in like 30 minutes should you loose central air system.
It was as cheap as strip heaters with the geothermal system. When on back up generator they make load management doable. On high they use 3800 watts each so we can run three set on low.
