Can adaptive AD/AP be changed to give stats based on damage type instead of build?

Currently, some of the new runes give adaptive AD or AP. I found that this is solely based on your build and nothing else. For example, if you have more bonus AD than AP from items, you get AD as your adaptive stat. Likewise, if you have more bonus AP than AD from items, you get AP as your adaptive stat. Usually, the ending builds of full tank champions like Maokai, Nautilus, Gragas, Poppy, Braum, Leona, etc. leave them with 0 bonus AD and 0 AP from items. I asked around and apparently if you have 0 of both, it defaults to AD.

This is really bad for AP caster tanks like Maokai, Nautilus, and Gragas because they highly prefer the AP from their runes due to scaling on their skills, but it's not usually optimal to fit an AP item like Zhonya, BV, or Liandry into their build. I am aware Doran's Ring is a thing, but it's always sold late game and you might want to sell it mid game for a ward slot. Other champions that get screwed by this are champions like Jhin, GP, and sometimes Corki/MF, who start Doran's Ring for mana regen but prefer to have AD runes to last hit and win early trades.

My suggestion is to change the adaptive "detector" to give AD or AP based on the type of damage you do. Kind of like a reverse Camille passive. If you have more physical damage dealt over the course of the game, you get AD. If you have more magic damage dealt over the course of the game, you get AP. If you have more true damage dealt over the course of the game, well...stop hacking. Or stop doing nothing but KSing with Darius ult lul.

What do you think?

Edit: It has come to my attention that Corki and Warwick build AD but do more magic damage than physical, and AP Trynd builds AP but does more physical damage than magic. In this case, have it only decide based on damage type of you have equal amounts of AD and AP from items.
