Not if you want the impedance to stay the same. And no, the directors are shorter than the driven element(radiator) and the reflector is longer. But as soon as you start putting all those bits of wire in close proximity everything starts affecting everything else.
Here’s a hint. Make a 1/4wave GP. It will on average outperform an an average inv-v dipole. On average being key. People did well with inv-v dipoles, but the height above ground, ground composition and ground slope can dramatically affect whether the radiation pattern from your antenna is a DX magnet or cloud warmer.
And the other hint: operate from a cliff edge or good slope facing the direction of the DX (not always possible though).
