Item Stacking Game Mode

I was thinking it might be pretty fun to do a game mode where you could build 6 of any item and the effects would stack. Like 6 deadmans plates movement speed stacking or 6 infinity edge or 6 zhonyas that you could use each separate. Updated gold income to hit builds faster or decreased item gold worth. and increased attack speed cap. Idk seems like it would be fun figuring out which items were more worth. gamemode could be called W.U.R.F. maybe lol. just an idea
