Here is a rough idea of the pipework layout:
When downstairs is off the flow which is common to both acts as a one pipe system for downstairs. If a non return valve could be introduced to the flow pipe in the second and subsequent radiators on the system then all should be ok...in theory.

That can't be, as you have no path for reverse circulation.
What must be happening is you are getting a gravity circulation into the rads, similar to a one pipe circuit.
The only way you would stop that is to cap the flow after the last downstairs rad, and run the new flow for the upstairs rads and connect somewhere around the same place as the zone valves.

It isn't a one pipe pipe system, and you can fit as many non return valves as you like, you wont stop parastatic circulation, unless you also stop wanted circulation as well.
It isn't a one pipe.
The heat is dribbling into each rad.
If you feel all the flows they will be hotter than the returns. Assumes you drawing is correct.
Also feel the return pipe prior to the zone valve for the ground floor circuit.
