Fan dipole..

about an inverted v that is only somewhat inverted? Would that not
give you a pattern more shaped like an egg?
The directivity of a half wave dipole over real ground varies with
height, and elevation angle. At the zenith it is omni directional, and at
lower elevations it has some directivity, but nothing like a dipole in
free space. Inclining the legs as in an inverted V dilutes the nulls
further and so reduces directivity, less so for large included angle.
So, the combination of an inverted V and mounting low to real ground
reduces directivity.
If you raise your dipole centre height, and decrease the included angle,
I expect that one will offset the other's effect on the pattern to some
extent.
