You are welcome to try that. Just make a few minor changes to your Printer Profile Custom G-code Startup G-code.
But I wouldn't recommend it. Heat makes metals and plastics change geometries, and calibrating while cold, or worse, while temps are changing... well, it's just a bad idea.

The bed warps significantly every time it heats up due to thermal expansion. Usually more than a layer height, sometimes 2. Probing before it's stabilized & while it's still changing defeats most of the purpose of probing to start with.

I'm not sure if this is something that is a prusa firmware limitation, or because I'm using Octiprint for my printing. Also, this goes under the category of "wouldn't it be nice if". Right now, my gcode starts pre-heating and waits till the pre-heating is done before it starts doing anything else. Wouldn't it be nice if it could go on and start doing the mesh bed leveling while it's pre-heating? Just a thought. It might be a limitation of gcode since it has to work on other systems too. I don't know enough about 3d printing to know.
