I dont know how you would be able to do that without it affecting the results of your tests. Ducting (depending on how far) could add a fair amount of added air flow restriction and depending on how its setup and wind speed and direction could actually add flow to what the fans could deliver on thier own.
Reason I asked is I have thought of in the future trying some rad tests of my own (for personal use) and the only way I thought of doing it was having the rad and fans only in 1 room and all the other equipment in an adjoining room with the exhaust from the rad going into the 2nd room through a hole in the divider wall (1st room is large enough in volume, its aprox 50'x14' finished basement that temps should be fairly stable as long as the furnace/AC is off). And at the other end of the room they are open through a standard doorway and short hall so the the pressure between them should be relatively equal, also neither has any windows so that outside wind shouldnt have any effect either.
The other way I thought would be the same setup only with everything in one room and just drawing air from the main room.
I believe that you will need a faily large room to draw your air from to be able to have fairly stable temps for the testing. I think getting a stable air temp to the rads for testing could be quite a problem also.
