if you proceed, you would want to make sure you don't trap oil in your manifold, and be sure to choose valves and piping rated for refrigerant use.
I forgot about those issues in spite of reading many previous discussions to that effect. Thanks for jogging my memory.

Since I am primarily interested in lowering my winter bills I think one unit downstairs would be a good place to start.
