View it more as a mixing rather than replacing.

Re: It's raining, it's pouring; this is getting boring....
Natural convection of a room is like a doughnut. In the winter that is warm air rising in the centre of the room and sinking down the cooler walls. In summer this reverses. Air travels up aided by the heat in the hot external walls and sinks in the centre of the room. For the fan to work at maximum efficiency you don't want to be fighting this natural process.

All anything like that does is to push against a gradient that immediately then reasserts itself.
Here's a stupid little idea that does work. In the corner under the highest point put a tube from a few inches below the ceiling to the ground where it plugs into a box holding a fan. The fan sucks the hot air down, and then this is the important part, it blows it out thru a slot at the bottom so that there is a flat fan of warm air that spreads out across the floor.
This will slide across the floor, sticking to the floor until it hits something, whether a chair or a person, whereupon the hot air starts to rise up around it.

Re: It's raining, it's pouring; this is getting boring....
Were I trying this, I'd use a pipe that wasn't too much of an eyesore, maybe fit it in the corner, or else fit a strip of plaster board in the corner at 45 degrees to the wall, then construct the box at the bottom so that box, strip et al were airtight. That really shouldn't cost much. It's going to be trial and error. Pick an expel air, or something of that ilk that isn't too expensive to run and will be able to be run for long periods, so not too powerful, then set up a slot at the bottom. Some experimenting will be necessary, but the end result will be well worth it.
You can use this trick to rob warm air from the top of one room, and blow it into another. Don't just poke a hole as tin the event of a fire, that will allow smoke thru. With the fan system, when it is off, there will be little or no flow thru the tube.
Another trick I will be doing is a free heat transfer between two rooms, where the heater is against the wall that seperates the two rooms.
I plan to poke two holes in the wall, one at floor level and the other about a metre up. A length of metal pipe about 4" diam will pass thru the hole at the bottom, up the back of the heater where it will get hot, and then back into the room I want heated. The pipe will be sealed, and the wall around it sealed too. The air in the tube is heated and rises, so it sets up a flow whereby a % of the air in the bedroom will be warmed, without the danger of smoke transfer. Best of all, it's cheap to set up, and free to run.
If you want to stop it, just put a flap over the bottom, or pop a ball into the bottom pipe.

Must admit I've made a few strange devices myself in the past to try and avoid expensive solutions to basically simple problems,normally using cheap materials or whatever was on hand or laid about.
Had a reasonable amount of success also,but once the solution began to appear too complex or complicated, I always knew when it was time to down tools and leave it to the experts.

How is that complicated?
It's exactly the same trick as bringing winter sunshine in. You put a box on the wall outside, and run a pipe thru the wall into it, one at top one at bottom. It heats up when the sun falls on it, and the air inside rises as it warms.
It's a simple, cheap and effective way of moving warm air from room to room without costing anything in running costs.

Lessee. It's a metal tube a metre long with a 90 degree bend at each end.

Re: It's raining, it's pouring; this is getting boring....
We do actually have a few doors here,but they seem to have fallen quite heavily of the back of a truck at some distant time in the past...(Valencian weekend job,say no more).
No two doors alike or even the same size,...one actually consists of bits of two others stuck together.
Don't seem to matter much whether they're open or closed, as the air seems to get past them quite nicely anyway,....so fortunately no great need to go knocking holes in the walls with associated pipework and all the rest thats involved.

Re: It's raining, it's pouring; this is getting boring....
Well, due to the high ceilings and low door lintels, the heat does not transfer well, and to heat the bedrooms we want, even with all the doors wide open it has no effect worth a damn.
The pipe is a simple way of transferring energy.

Re: It's raining, it's pouring; this is getting boring....
Well after an appalling wet and cold winter spring is finally showing through.
It was awful... damp cold ... much worse than the UK where buildings and heating systems can cope with it.
Hopefully the next backend will be warmer
