The jet is not the problem - it is the huge bang when the HEAT round goes off. While part of the explosive force is directed, the rest is not. The secondary effect is considerable.
German tests vs add-on-armour in WWII showed that a 75mm HEAT round could shatter armour plate and rip the mounts apart, so even that would only be a one-shot-protection.
Rather than a little hole in one bag, you would have the entire side or front of the tank stripped of bags, leaving large areas unprotected.
Try looking up some HEAT detonations on the web to see the effects
