This is no ryl possible. the only way u can do this is coding every exception to make it stable so with inventory clicks and setting item amounts removing old items etc

Here, I made both a skript-mirror effect and a function for it! Have fun c:
(Untested)

effect stack [all] %itemstack% in %player%'[s] inventory:
    trigger:
        loop all items in expr-2's inventory:
            if loop-item is expr-1:
                add 1 to {_items}
                set loop-item to air
                if expr-2's inventory doesn't contain expr-1:
                    stop loop
        loop all items in expr-2's inventory:
            if loop-item is air:
                set {_item} to expr-1 * {_items}
                set loop-item to {_item}
                stop loop

function stackItem(i: item, p: player):
    loop all items in {_p}'s inventory:
        if loop-item is {_i}:
            add 1 to {_items}
            set loop-item to air
            if {_p}'s inventory doesn't contain {_i}:
                stop loop
    loop all items in {_p}'s inventory:
        if loop-item is air:
            set {_item} to {_i} * {_items}
            set loop-item to {_item}
            stop loop
