Is it possible to build an omnidirectional receiving antenna with
gain?
TV transmitting antennas are generally omnidirectional, and have gain. They
do this by concentrating all energy along the horizon. In fact, some work so
well that they put up a secondary antenna at 100ft or so to take care of
people who live close by.

If you want to talk about practicality, it would be easy to build one at 2
meters. Forget about it on 160m.
