[Suggestion] Orb of Ascension - Upgrades Unique Item to Higher Base

I would like to propose a new currency item "Orb of Ascension" that upgrades a low-level unique item to a higher base. This would allow a player to transform an early game unique found in the campaign to an endgame unique. This is similar to the Horadric Cube recipe for upgrading uniques in D2.

Orb of Ascension

* Can only be used on unique items below item level 60.
* Selects a higher-tier base item of the same class.
* Implicit modifiers are replaced with those of the new base.
* Re-rolls numeric values of unique mods to match new base’s item level.
* Cannot be used on corrupted items.

Function: Upgrades a low-level unique item to a higher-tier base item of the same type, preserving its unique mods but recalculating values based on the new base.

Revitalizes early uniques and lets players scale beloved low-level uniques into endgame viability.

Personally I don't dislike the idea, but I think the problem is that most uniques are just bad. They're not even weak, just straight up bad when you compare to any random rare. I've been saying this since first day of 0.2 when we got a hundred more uniques and you can count on the finger of a single hand how many of those ended up being used (not counting the unique charms, those are nice)

Most uniques in the game need to either get completely reworked or simply removed from the game
