That all works surprisingly well, didn't have to do anything special except keep the doors open to the rooms I want to heat. But the area I can't get the heat to is on the same floor as the LR, in an ell. Not practical to route either hot or cold air through the cellar because of the layout, nor through the attic. It sounds like the best I can do is one of those fans in the corner of the doorframe. I'll be pushing the warmer air, not quite as efficient as pushing cold, but better than nothing.
See what others here think of cutting a cold air return ( maybe just a 12"x12" floor register) in the room/rooms you cant heat (that opens down to the basement) to draw off some cold air & suck warm air in there.
