Bring back old League in custom

Well, this isn't really about "Maps and Modes" but i dunno where i could write this ...

Some will say "past is past" and that's true, but sometimes you keep this as a personnal memory and you're having a lot of pleasure to bring it back to your mind :) So, here a thing that could be awesome : bring back old League of Legends patch, since the beginning, with a different launcher (almost like PBE) but only for custom games ! I'm pretty sure everyone of you guys know some Dofus private server : to create them, you need to download the Dofus database then you can build your own Dofus server, only for yourself (or friends with your IP), so what about this on LoL ??

Rito you could make us download the full old patches, you know them, the ones with ATmog's , Force of Nature , Innervating Locket (drug item), the ones with round-the-map-sneaky Q's (), the stacking HP Sion ... and people could have a lot of fun and pleasure to redo what's impossible to do right know : isn't League for fun ?

Of course, all these patches could be available only in custom mode, and you could only play with friends on the same network, but i would really really be awesome, i just learned to play on the old Dota-like map, where can i find it now ?

You guys did an awesome job since the beginning, but i think League Of Legends is still a very very closed game, and you know somedays you will be overtaken by some online videogames developper, but i think you got enough money and you can start to "open" the League, at least create a full customable mode, or a map editor ... would be very awesome :)

Thanks for reading me, i don't really mind if you guys agree or not, that's just my opinion on the question, but you can leave a comment to share your old League memoris and missings ;)
