New Champ Pure Support?

Seeing what Kalista did with her ult I thought about the possibility of a new champ that merges with other champs. My idea Was to have a champ that would essentially fuse with another and increase their size, giving them a small size increase and a small aura to let people know whats up. Now when they fuse the fused to champ would receive a large stat increase for every stat and i mean every stat (ad as ap ms mr Armor Max health/mana health/mana regen cdr) but this merging would only last for 10 secs and after ward both champs would have detracted stats for a short time with a huge cooldown. This champ could also have a Q that slows and deal moderate damage, a W that's a bubble which reduces incoming damage and boosts as and movement speed for a short time, an E that's a a small wall no bigger that Anivias basic wall that blocks movement and projectiles except ults which break through the wall destroying it and dealing reduced damage, and a passive that is a health regen field for allied champs large enough to cover the lane this champ would be in.
