Equipment offering different bonuses based on slot

Hello. I am not Sure if this kind of plugin exists yet, so I am asking here, firstly if anyone knows of a plugin that already does something like this (or close to it)... and if not, if anyone could help me by making it?

As a note, I am using Hime-EquipSlotsCore (for multiples of the same kind of slot. And to give equips the ability to go into multiple slots)

My desired effect is to be able to have 4 weapon slots on each character ... 1 "equipped" and 3 "unequipped" kind of like having them have their own pockets. (Think Final Fantasy 1 NES)
Similarly, I will be having 4 armor slots, (1 Torso, 1 Helm, 1 Bracelet and 1 Shield.) and I will be having all of those armors being able to go in ANY of those 4 slots (even if its the wrong one, but only giving stats if in the right one).

So... my equip slots would look like this.

E - Weapon
UE - Weapon
UE - Weapon
UE - Weapon
Torso -
Hands -
Shield -
Helm -

I can accomplish all of that already...
What I need is the ability to have the gear give differing stats based on the slot they are in. So if you have a weapon in the UE - Weapon Slot, it gives 0 stat changes but adds a skill. And if a Helmet is in the bracelet slot, give 0 stats changes.

So basically, I need a notetag that says

<equipslot>
if slot 3; atk + 5
if slot 5; add skill[3]
</equipslot>

Is this possible with Evals/lunatic Mode or anything in Yanfly's current plugins?
Any other possibilities???
Thanks ahead of time!
