This doesn't specifically answer the question in the title, but from the body of your question I would say it's possible, if you had an electric push/pull configuration with a motor in the nose and one in the tail, or at the back of a fuselage pod with booms like a Cessna Skymaster.
The aft facing motor could use simple fixed pitch folding propeller that ...

First, you should state whether you are designing an engine (increasing the TIT) or if you are doing an off design calculation for an existing engine.
In the case of design we gas turbine performance engineers call this design point analysis, increasing the TIT indeed would increase the efficiency, but this would require an increase of the pressure (OPR, ...

Large airliners don't fly at slower speeds.
It's simple economics.
If you have to connect two destinations 10,000 miles apart, you'll do maybe 2 round trips a week. Your passengers have no other choice, except a flight that takes even longer. You also have the luxury of flying between two very large cities.
If you have to connect two destinations 100 ...

The jet engine efficiency is unfortunately more complicated than just a one-to-one function between static Turbine Inlet Temperature and efficiency. Thermodynamic efficiency of a turbine engine is defined as the useful generated power extracted from the chemical energy added by the fuel.
The following is extracted from a paper format uni book on aircraft ...
