Buy a ceiling fan. They will reverse in direction blowing heat down in the
winter and up in the summer. Google "Convection". What you are proposing
is setting up a circulation of the air in the room so that the cold air
mixes with the warm and you approximate an even temperature throughout the
room. That is precisely what ceilings fans are made to do. And they won't
cost you much different than what you are proposing and will do a MUCH more
efficient job of it.
A modicum of scotch will make the temperature difference far less
noticeable....
