Why didn't you just buy a complete car as a donor?

The only limitation I can think of for orientation is keeping air bubbles or voids out of the liquid cooling system. You'll toast the power devices in a heartbeat without coolant contacting them.

Or vacuum, then fill.

Ok, that helps. I plan on splitting them up, the rear area is actually pretty spacious but I'm not sure how much weight can go back there.
I suppose I could put the charge controller and inverter in the rear but that means running coolant hoses the length of the car which I'd like to avoid.

You want the inverter intimate with the motor for a number of electrical engineering reasons. Putting it in the trunk, 10-12 feet away, is a bad idea.

Charge controller remoting is fine.

The charge controller and DC-DC are both inside the PDM on a Leaf is my understanding.

In that case, the DC-DC can't move on its own without a lot of butchery.

"minimal" in English units

"short" if you use metric

My understanding from Nagoya University's Youtube teardown is that there may be two inverter heights if you're pressed for a couple of mm of clearance, with the later model being fewer "layers" of circuitry inside. Not sure what year it changed.
