Considering that a new radiator is shown on MR Cycle's microfiche at $491.35, which would solve your problem at a price, I'd be looking for another radiator shop that would, if they could, replace the entire core using your original tanks. We used to send customer's radiators out every other day to be re-cored. It then became more cost-effective to replace with an aftermarket radiator, but I havent seen any aftermarket radiators for motorcycles. This same automotive radiator shop repaired a seeping tube in the core of my '00 ZRX1100 11 years ago, is still not leaking.
You say your radiator was damaged in an accident. Was the repair covered by insurance? If so I'd contact my agent and tell them the radiator they paid for has been unsuccessful--twice, and see if they'll provide assistance for a new one.
I'm not saying closing off one of your radiator's tubes will cause a problem...but I'm not saying it won't run hotter in certain conditions either. I'm not fond of sacrificing radiator cooling ability regardless of price or what other's experiences doing so have been.
