The core would saturate, probably blowing the fuse. However if you had two 120v variacs you could probably use a series configuration, preferably mechanically ganged to balance load between them.

Depending on where you get the variac, it might not be wired the way you think. I would make sure the neutral wire is really neutral and not going to the HOT terminal of your outlet. I would also make sure the neutral is not connected to the grounding wire of your chassis.

How much did you want to spend on a variable transformer. You can buy them new from Westek Electronics in Melbourne. I'm sure you can source a local supplier if you are elsewhere.
