Haven’t tried it, but this seems like something you can customize ingame at any time with the builtin map editor.

See the “setting up research” on the editor wiki page:

Edit: you’d probably have to give yourself the necessary modular armor, roboport and initial bots.

Try Companion Drones (don't have a link to hand) - gives you a pair of very capable personal drones that can attack/defend as well as filling in blueprints.
