I don't have the formulas to calculate the energy required for orbital plane changes, but I know the 8000# of OMS fuel carried by the shuttle is sufficient to change it's orbital plane by 1 degree or so.
So on the back of this envelope, assuming the ISS has a mass ten times that of the shuttle orbiter, it would take 2 1/4 million pounds of fuel to accomplish that task.
