That could very well work, as long as you don't have any "tuning circuits" in the bottom of the antenna that require a connection to the ground plane.
For an example, a 5/8's wave antenna may have an L circuit, which would need to be connected to both the monopole and the ground plane.
You could also just use a tuner instead, placing the tuning circuit farther away (so more loss over the coax), but still should work about the same.
A NMO mount isn't very tall. That's what I use.
