 DO NOT USE A STEEL ANYTHING! You are likely to damage the piston and/or the thread of the plug hole.  Use something like aluminium or wood. This is unlikely to be successful, as the force you can put on the piston will be less than the connecting rod will with you swinging on the crank. Mind you, both at the same time might help.
One point is that there is no guarantee that the cylinder holding oil is the problem one - the others may not be holding simply because the exhaust valve, which is lower than the plug hole, is at least slightly open.  Did you manage to blow any water out of any cylinder?
I think it may be about head off time before you damage something, although just leaving it to soak in penetrating oil or diesel may work after a week or so.
I would think that even if you free it, you would want to pull the head off to check what the problem was anyway, so you might as well do it sooner rather than later - it is not a very big job.
