They do give you more power with more health.
No it would actually hinder the weapons.

Let's say that you have 75,000HP and you get smacked hard by an attack, we'll use Mega Graviton for an example. This attack does 7/16 of your total HP, not current. Now that you're in critical your weapons (the ones that base their power on current HP) are doing very low damage because your HP is low. Without BHPL one curaga, x-potion, etc. will bring you back to full health and max the power of your Celestial Weapons. With BHPL you must take more turns to restore your character's health and that can be fatal if you're facing somebody such as Penance.

This is just one example of many obviously but it's something to keep in mind.
