My idea is to have a robot that has one job, to upgrade assemblers, miners, robots, upgrade modules and anything else that can be replaced with a better version of itself.

Basically you have a building that you choose what you want to upgrade, you put in the new items and the robots will auto upgrade everything that needs it and put the obsolete stuff back in this building. Is this possible?

yes, is possible, I don't know how to work with logistic area, but you can find entities in that area like game.findentitiesfiltered{area = {logisticArea}, name= "assembler-machine"}
I like this idea, i think you can find a "item" in a logistic storage and upgrade a "random" entity.

If you have questions, ask here

that would be really cool a type of robot and a chest to put the upgrades in and one to put the old stuff
