I do NOT condone this, this will give you a false headset and no real driving from behind to bring the back up and into frame.
This horse needs to be pushed out. He needs more impulsion to really reach under himself with his hocks and stretch into the bridle before you start to think about collecting him at slower speeds. Remember that it takes a lot of strength to maintain true collection at the slower jog and lope.
Any horse can break at the poll--that's not the point of correct riding. Correct riding is from back to front, pushing the horse up into your hands so he uses himself better.
Also keep in mind that the type of hunters you're aiming for us AQHA hunters, I assume, as you posted a video of AQHA HUS. It is a world of a difference from USEF hunters.
