Not sure you grasp the issue here. The objective is to make AC value a consideration (and not only resistances or other modifiers). So yes, if AC protects more from melee, it will be valued higher compared to, say, fire resistance. If you reduce AC, players will certainly not take it more into consideration.
The fact that melee damage plays a small role in the spectrum of dangers is a different matter entirely. While it might be a good idea to change that, it is not clear how that can be achieved without other (possibly unwanted) consequences.
The first obvious idea is to make phasing less available, but then this has always been a feature of Angband and it is unclear if that, in the end, really would make players want to wear heavier armour.
Back when Magnate made this change my idea was to make npc archers more impactful, effectively introducing physical ranged damge into the spectrum, against which armor class would help of course. As it stands, everything dangerous is magic and elemental.
