I saw in your vid that you didn't plan on keeping the coffee can. Wise choice
power vs manual:
A MC and booster don't "work together". They are independant parts of a system. The booster exists ONLY to convert pedal travel into a pushing force gainst the MC. In older systems there was no booster, your pedal moved the MC directly.
The difference between a boosted and non-boosted MC is the size of the piston - the action ratio, i suppose. A MC designed to have a booster needs to be pushed harder than one that does not. If you simply take a MC from a scrap yard that was designed for a non-power brake car, then mount it where your pedal's pin pushes the booster, you'll get braking force. You would need an adapter plate made because that MC will not have the same holes as your where your booster mounts on the firewall.
