How difficult will it be to build a 'hybrid' Jet engine?

TL;DR Summary

Can we build a jet engine which will be able to handle both Kerosene and (gaseous) Hydrogen as fuel? After burning the kerosene for a while, Hydrogen will take over as the fuel, burning to produce the exhaust gas and resulting thrust.

Hi,
Here is a question - somewhat futuristic and at the moment, hypothetical.
How difficult will it be to build a 'hybrid' Jet (turbofan) engine? The engine should be able to handle both Kerosene and (gaseous) Hydrogen as fuel. After burning the kerosene for a while, Hydrogen will take over as the fuel, burning to produce the exhaust gas and resulting thrust. Let me clarify. Imagine, there are excess electricity produced by the turbine(s) of the engine(s). This electricity will be used to produce Hydrogen by electrolysis of water and Hydrogen gas (so produced), in turn, will be fed into the engine. There is obviously the question of feasibility of producing enough Hydrogen .But the focus of my question really is: assuming there are enough supply, can an engine (with current design/architecture) be suitably modified to achieve this?

I used to do consulting work with a local patent attorney. Almost all of the attempts gain efficiency were a "partial" perpetual motion machine. I remember very well elderly farmer who was convinced he could add an air compressor to his system and regeneratively run it to his advantage. I convinced him this was unlikely and saved him some money...although maybe he would have been happier working on it...
Anyhow your jet seems very unlikely to be useful...convince me otherwise.

Not at PF. That kind of discussion is not allowed here. Thread will remain closed.
