I am a newbie in EZNEC (eznec.com) antenna modeling, but I tried it
with a known-functional arrangement, a 20m dipole at 30 feet.

When I rotated one leg as you described, the feed point impedance came
down from 75 ohms, the resonant freq went up slightly out-of-band and
the pattern was nearly circular.

I dropped the antenna to 25 feet and the resonant freq came down into
the band and the impedance hit 50 ohms almost on the nose.

For all practical purposes, your change is close to an omni. One
issue: It has a fairly high take-off angle at 48 degrees. Some
people do not worry about take-off angle, the elevation angle of
maximum radiation. This is because the differences are only a few
dB. It takes 6 dB to make a one s-unit change, so you're not totally
ruining your chances for a QSO if you're down a few.
