Your idea makes perfect sense.

One thing to keep in mind is that having the point of maximum
current lower on the antenna could result in higher ground losses.

This makes it a tradeoff between maximizing low takeoff angle
radiation from the vertical partof the radiator and minimizing
ground losses.

All rights reversed.
