That's isn't how thermodynamics works.

It could have a reduced thermal signature but infrared cameras are so absurdly sensitive so it isn't obvious to me that a reduction would be a big advantage.

Diesel-electric would have the same redundancy advantages: https://oshkoshdefense.com/engineering-solutions/propulse/

Diesel is relatively hard to get to burn as liquid fuels go... lithium chemistry batteries aren't particularly known for being fire free.
