Game Ending Items , Gold Sharing Items, Unlockable Upgrades, Item Combos

This idea is not well polished but I notice alot of times especially in lower level game play one person or the entire team is not able to end the game due to poor team composition or trolls in the match who refuse to follow meta. This idea does not offer imbalance but instead a way to keep increasing power with extensive gold penalties. If you wanted to combine 6 complete legendary items such as Bloodthirster to get a shield and overheal, Randuins Omen to slow enemies that attack you and a active that will slow enemies, Trinity force to increase movespeed and apply sheen while providing movespeed, phantom dancer to move through units and increase movespeed, black cleaver to make all abilities and attacks sunder armor, and gaurdian angel to revive from death. This item would not increase in statistics or have any reason to be bought except clearing up 5 item slots and giving enhanced ability to end the game. It could be very expensive such as 10,000 gold to combine these items into another item called "all spark" or " big bang " or "something creative". Ability to combine powerful items for extra gold such as Trinity force + Runaans Hurricane + Bloodthirster to create Noxian Corruption, or Demacian Justice item. Demacian Justice and Noxian Corruption will have all of the passives and actives of the items combined but offer no bonus stats for those long 1 hour- 2 hour games that are difficult to end when your build is finished and your gold pool ends up being over 10,000 wasted gold. Gold sharing items that can be built by ADCS to help supports along the way, for every cs shares 3 gold. Items that can be purchased that will cost 2,000 gold to give everyone on your team 300 gold. Upgrades such as item slot 6 the item slot will cost 1,000 while item slot 7 will cost 2,000 and item slot 8 will cost 5,000. Item combinations similar to trinity force for other items like Bloodthirster + Essence Reaver + Hydra for Bloodthirsty Essence Hydra , or maybe a cooler more thought out name. For each AD item like trinity force there should be a equal AP item such as Zhonyas + Liandrys + Rabdons to make Arcane Tri-force.
