YES! I'm doing exactly that with my Tee vertical for 160M. It roughly 
doubles the SWR bandwidth of that antenna.

The effectiveness of vertical antennas is STRONGLY dependent on ground 
conductivity both around the antenna AND in the far field in the 
direction of radiation. I have lousy soil (rock) so 160 is the only band 
on which I find verticals better than horizontal ones.
