You really should model it with EZNEC or a similar program, but I can
tell you this: Even at a 45 degree apex angle, an inverted vee is
almost perfectly omnidirectional. I'm thinking this is not good for
the driven element of a yagi configured like you have it because some
of the energy will be radiated off to the side of the yagi instead of
toward the desired direction. A conventional dipole driven element
radiates almost no energy directly off to the side.

I'm no great expert with this, but I'm pretty sure it won't work as
well as you are hoping.
