The the 618°C temperature that you quote for the RR300 is MGT (measured gas temperature) which is actually the turbine outlet temperature. As such it will be 2-300° C below the Turbine inlet temperature. Small gas turbines like the RR300 with uncooled turbine blades have turbine inlet temperatures in the range of 850-1050°C.
A gas turbine with 618°C inlet temperature would be lucky to reach 15% efficiency. And with a pressure-sapping heat exchanger to heat the air instead of a combustor (not to mention reduced turbine mass flow due to absence of fuel) the efficiency would likely be even worse.
