I have no doubt it would work but getting it past the stupid and useless ethanol production agency is a whole other matter.

The car was featured in the 2015 MotoGP season as the official safety car for the series and was released for the commercial market in 2016.[8] As per BMW example, current engine developments featuring water injection seem to concentrate on the effect of “Performance Improvement”. But by the mid 2020s, engine development will shift focus also on improved fuel consumption, due to the pressure on CO2 emissions reduction and related regulations.[9][10]
Bosch, which co-developed the technology with BMW, offers a water injection system named WaterBoost for other manufacturers. The company claims up to 5% increase in engine performance, up to 4% decrease in CO2 emissions and up to 13% improvement in fuel economy.[11] Similar results were reported in "Water Injection - High Power and High Efficiency combined"[12]

With the old Chrystlers the problem was that owners would forget to fill the water tank. As a result they would blow the engine.
A way to get around this is to condense water out of the exhaust.
