I did exactly what you describe with my 27m (90 ft) mast.
It apparently worked fine (I didn't have another antenna
to compare it to.)  I built a homebrew tuner.
I don't know of a commercial one that could handle the
high voltages.  I later decided this was too much
trouble and installed a relay at the 60 foot level that
allowed it to run as a conventional vertical on 80 when
the relay was open.
