I would think that a cooling failure on one rotor would cause the whole engine to fail after a short time. I don't think you could continue to run it for a long time. Keep in mind that if you put two cooling systems in, you are twice as likely to have one of them fail. If a single cooling system failure brings down the power plant, you end up reducing the reliability rather than increasing it.
