Can you use Electromagnetism to 'Boost' the power of a permanent magnet like rare earth magnets?

Simple question. Also if so how much of a boost per volt/winding.

Yes, but how much depends on too many variables to give an answer - like the saturation flux density for the magnetic circuit for a start

If you want to make an electro-magnet, do that. If you've got a powerful magnet use that. Trying to combine the two is not going to be very helpful to you.
