Anything that will increase the current in the wire below top-loading
is a good idea.

* Does this Idea actually Work ?

I don't know the answer. A ferrite inductor will increase the magnitude
of inductance over an air-core coil and top-loading will increase the
current in the wire part of the antenna. It's an interesting idea
assuming that antennas are reciprocal for transmitting and receiving.
