One thought, and it's just theoretical, is to jack up the back of the car, so the ends of the hoses are higher than the heater core. Or close to it. Then get a submersible pump from Harbor Freight, put it in a 5-gallon bucket or bigger filled with your cleaning solution. Connect the output from the pump to one of the rad hoses, and run a hose from the other rad hose back into the bucket. turn it on and let it circulate for a while. In theory that should work.
Now, what kind of solution to use?
Good luck!

Hey Pipe!
Shout. The stain remover. I've been following the 2 vids on utoob. Guy bought a car with coolant/oil mixture... and he used up 2 jigs of the stuff, and mixed with water. The engine was in... car running. Granted, it's a 911... same concept.

That's the first vid.
I like your idea... rear end raised. If you can... try to get everything sealed up so the water has a little pressure. The guy on the video did around 2-3 flushes with the Shout/water mix... then flushed it garden hose a couple of times until it ran clear... then a flush with distilled water.
The challenge I see is the heater core... for it may be closed because the water temp will be cold... tepid. Unless you can get around that... you'll have a little residual coolant in the system. Very small given the 6 gallons they hold.
Good luck!
