Maybe reducing some of the AC whilst pumping HP to make up for that has been done with that in mind in parts too.

It has been discussed a lot that you can't do that without messing up the balance elsewhere. Not all attacks target AC. Anything that attacks saves or HP directly gets nerfed when you lower AC's.
