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.
