PROBABLY what I will do, probably, leave both tanks where they are and just attach a hose line to the hose nipple on the overflow on the "overflow" tank and just run it to a catch can were it is accessible and be done with it? A definite maybe or maybe a probable probability?

My only comment - if you use one of the catch tanks that feeds from the bottom, and you plumb it up to your radiator cap on what I called the "expansion tank", then it will suck and blow in and out of your "closed circuit" system, and you won't squirt coolant on the ground.
It may be a little fluid , or it may be a lot.
If your 3rd "catch tank" feeds in/out of the top of the thrid (catch) tank, then you will have to manually pour the fluid back (somewhere) - either into the system or into the toilet.

My system is a hybrid of pictures #2 and #3 - the basic difference is that the "expansion tank" in the middle paicture is only half full, and the "overflow tank" in #3 catches what very little fluid is ejected during regular operatations.
