I vaguely think that you only need a throttle position sensor and a map sensor
to do a reasonable job of EFI. However, you WILL need the crankshaft position
sensor, which means you need the flywheel, transfer case and the actual
sensor.

As you know, these are a bummer to remove from the mini, especially in a scrap
yard. Still, it is highly doable.
