That is an interesting thought, but my luck the Pistons would tag the valves bending them.
Pulling the injectors is easy and much safer.
I'd first pull the injectors
Spin her over by hand and put some oil in the cylinders, spin by hand a few times and then use the starter, put a rag over the injectors holes to catch the water and oil slurry, you will be surprised how far it can be shot if you don't.
Then put injectors back in and run it a few minutes, change the oil even if it's not milky, then run it five min until hot, any evidence of milky at all, change it, repeat until oil is clear.
Cylinder walls will form a layer of rust amazingly fast, even with fresh water, there is a time limit, you need to get oil in there fast and stop the rust. The rust will be cleaned off by the rings very quickly, but it can lead to bore polishing as it may wear away the crosshatching, it's job is to hold oil for both compression and lubrication, crosshatch wears off, engine has a lot of blow by, oil gets filthy fast, oil temps run high and engine consumes oil.
Only fix is to disassemble engine and hone the cylinders.
