However as stated in the first paragraph the druid woudl not get any benefit to hit points. The CON that the druid aquires while in animal form does not affect their HPs, therefore an increase in that CON would not adust their HPs.
Actually, I think you're misreading the text here. Here's what you quoted at the top of the thread:
"The druid retains her own Intelligence, Wisdom, and Charisma scores, level and classes, hit points (despite any change in her Constitution score), alignment, base attack bonus, and base save bonuses. (New Strength, Dexterity, and Constitution scores may affect final attack and save bonuses.)"
It seems pretty clear to me that it's not preventing changes in CON while
in animal form from affecting HP. Rather, it's saying that the change in CON
while changing to animal form doesn't change the druid's HP. Only that specific change in CON is involved. Any other changes while in animal form, such as Endurance, would alter HP accordingly. The changes are relative rather than absolute; simply add 1 HP/level for every +2 to CON, and subtract 1 HP/level for every -2 to CON.
Among other problems with your interpretation would be to provide the druid in animal form a near-total immunity to the effects of Constitution damage. I don't think that reducing a 20 CON druid to 1 CON and having her retain all her hit points is a good idea.
