The engine itself would probably not be able to handle the higher pressures unless it was built from scratch to do that ($$$$).

And the metallurgy required to handle the thermal shock of injecting water into a hot engine would probably be cost prohibitive if it could be done.
Damned thermodynamics is a PITA.
