Idea: Hextech Crafting Gem Mine

So this idea has popped to mind about Hextech Crafting and the possibility of obtaining exclusive skins. Now we all know League has some limited edition skins that are virtually impossible to get (Black Alistar, Human Ryze, Pax TF etc) especially now that Riot has disabled all old skin codes. Now you may think "Ok? Those who got it deserve it for being veterans of the game, it credits their status as being the earliest players of League of Legends"

This I 100% agree with. BUT! What I also don't like is the virtual impossibility of completing a collection due to this ideology. So what can we do? Well, remember when the PROJECT skins came out last year? Those who bought them early during release got a permanent border across the loading screen for that skin.

As you can see, this credits the buyers who bought the skin during the promotion and differentiates from those who bought it at a later time.

I think you already know where I'm getting with this. Now with the limited edition skins, why not add them to hextech crafting to be only exclusively obtained through there? With a RIDICULOUSLY rare chance of getting even one, like winning the lottery. Then if you do get one limited edition skin, e.g. Black Alistar, you will need something like 25 rare gems to unlock that shard ONLY if you managed to get the shard from a chest first. See how difficult that sounds? But at least it gives you the possibility, that chance, that thrill of opening a box and just hoping for it.

And to secure the credibility of those players who got the limited edition skins at the original time, the skins obtained through hextech crafting will have a hextech border at loading screen similar to what they did with the PROJECT skins. This allows players to once again have the chance to revive these great classic skins and complete collections plus keeping the credibility of the players who got the skins originally in the past.

I love Hextech Crafting and well done to Riot for implementing this, I'm just throwing ideas in the barrel to really spice things up for thrill and excitement! :D

Let me know what you guys think

TL;DR Place limited edition skins in Hextech Crafting with an extremely low chance of getting the shard. If limited edition shard is obtained, it will take X number of gems to unlock it permanently. Hextech border placed around the limited skin during loading screen to retain credibility of original owners of such rare skin.

EDIT: added TL;DR
