Thanks again all for your input and time.

Yes, that procedure will work. You actually can clean out the coolant tank before hand and fill to cold mark before you start to top of system/engine running. That way the moment you put the cap on the radiator (FULL) the external tank will be ready and in service.
Instead of physically removing the overflow tank, you can flush it out with the water hose, then use a wet/dry vacuum to remove water/residue, using a small suction hose. I picked up clear 3/8" ID hose at the local hardware store to use with the shop vacuum. 2 or 3 feet will do it. Then partially fill it with a 50% mix of water/coolant.
I see your car is a 2011. How long did you go before the first coolant flush? time and mileage? First flush ever?
Oh when you do the drain the radiator then add distilled water deal, you have to repeat many times to do a proper flush, like 5-7 times. Draining the radiator might remove 30-40% of the total coolant volume. Still coolant in the engine, hoses, and heater core. There are better ways to "flush the coolant system".
Oh and it goes without saying, immediately wash off any coolant or mixture that splashes. It will damage/remove paint with time.
