Well, you'd have a "slant" or "tilt" polarized radiator. You could make the
top horizontal wire a 1/4 wavelength and let it be an elevated radial and
treat the vertical wire (probably bent horizontal at some lower altitude) as
a vertical radiator, but you'd still have a "tilt" polarized radiator
because of the horizontal and vertical high currents at high elevations.

Wouldn't feeding it up high in the corner like that at least eliminate the
need for radials?
