Sounds like a good plan to me, too. I will add this: comfort in a room
is a matter of radiated heat. Using a furnace or radiators to heat the
air is only the first step of comfort. It's only when the heated air
has heated the walls, furnishings, etc that comfort is achieved. It's
the heat radiated from the walls, etc that does the most to warm you.
So, doing it directly with radiant heaters makes a lot of sense.
