I do plan on wrapping some insulation around the kettle and just tie it on so I can remove it for the boil.
I want to use the RIMS tube to get the water up to temp for a couple of reasons. The cost of propane, which won't be offset by only going partially electric, but more important to me is that I can set it up and forget about it for a couple of hours while it gets hot and if I forget about it for longer than that there is no harm. This afternoon with no insulation and ambient temperature at around 55 degrees it a little less than 2.5 hours to get 9 gal to 160 degrees. It should be better than that with insulation.
