Looking for an addon or someone to make it

[Knowlyfe 0]

So i'm looking for either an addon that already does this or if maybe some generous LUA inclined individual could make it for me. I'm pretty noob when it comes to remember stat values and such ( i don't know why, every time i look them up or just equip something else to show me the value i feel like its super easy but whatever). I want it to show the values in the tooltip kind of telling you "hey, by getting 'x', you're also getting 'y'"

i made this example, just pretend on the right its some piece of gear with same values but leather
