u/Far-Tangerine-2690

I am contemplating a new build and was wondering if I could use 2 x U-flow radiators connected as per the image to create a X-flow radiator.

I am thinking about using 2 x dual 180mm radiators in a Haven BF-360 Flow. From what I can eyeball the radiator port side will overlap each other so was thinking if I could just connect the ports directly to each other I could possibly use the drain ports of the radiators to create a cross flow rad setup. Am I missing something or would this work perfectly fine?
