Playing 4th suit forcing, most play 2♦ as a simple preference, 3♦ as invitational, game forcing sequences go through 2♠.
It's also reasonable to play a (much rarer these days) style like Pavlicek recommended where 3♦ is forcing, and 2♠ followed by 3d is invitational. Surely it's best to play these sequences differently than have both be GF.

In your system, what's worse, hiding a 5 card heart suit which is an unbelievable bid, or make a small underbid by making a 2♦ preference on the 2nd round.
Agree hiding 5 cd hearts is just plain nutty even having massive system holes.
