I'm sure this will increase the transformer's power rating some, but
the problem is the oil can only remove heat from the outside of the
unit, not from deep inside. That's where overheating would occur
first. Heat transfer from the inside to the outside is slow and a
surge might do you in. Also, the oil itself would have to be cooled
if you're going to operate for any length of time.
Better to just get a bigger transformer.
