well, I'm not sure if I made myself clear: the setup with brake lines and valves was for testing the MC itself, not for "bench-bleeding". I thought you wanted to see if the MC is good or not!
If all you want is redo the bleeding, your setup is commonly recognized (although I don't think it's that good, since you may get some air when swapping lines).

 

The Motive brake bleeder is one of my favorite tools. I practically beg my friends over to bleed their brakes. I chased a very small coolant leak for months. The Motive finally saved the day. I took an extra radiator cap and cut off the lower seal so the overflow tube would be open to the coolant tank but not atmosphere. Then I connected the Motive to the overflow tube and pumped it up to five pounds. I was able to spot the leak. Yes, you can buy a purpose made coolant system leak finder but this does the same thing for the price of an extra radiator cap.

Get one, you will like it.
