Yes, you can make an isolation transformer as you described it. It will
probably not be as efficient as commercial ones due to skimping on the core
to save manufacturing costs. The other easier way to make an isolation
transformer is to run a pair of MOTs back to back: hook the secondaries
together, run power into one primary, and take it out of the other primary.
Wastes a few more watts & is heavier, but it saves a lot of work.
