Summoner and Pet- Perfect Duo

First off, I would like to give credit to the creator of the video I linked, Jeremy "Gaming Curios", because it was watching his video that I thought of these ideas.

The main focus of the video is the idea of a champion with a pet that is a permanent part of his/her kit. The pet would attack with the summoner and do as commanded. Now at first glance this does sound like Kindred , but the idea is more like a permanent Tibbers on Annie . At first my main ideas that pet and the summoner would each have their own HP and that if the pet died the champion's ultimate would simply revive the pet. This didn't really fit what I thought would be interesting so I scrapped it. Another idea was if the pet died it wouldn't revive until the summoner died as well. Although interesting it wouldn't really display the bond the two have. Having the two share HP makes the most sense, but it still didn't seem right. I put a pin in that part and decided to approach it later.

Other ideas I had were the summoner being AP and the pet being AD with its own stats with the ultimate will combining both the two for a short duration and the new creature gains both party's stats. Or the champion wargs, like GoT, into the pet. The champion gains different abilities and better control of the pet for a short duration. Both were interesting, but didn't exactly feel clever or unique. Having the passive be where the closer the two are together the easier it is to play. This could include better combos or slight stat, health, or mana increase. With each half having their own health this would encourage players to keep the pet safe.

The I thought that the summoner can "train" their pet in game. Similar to Gangplank's ult you'd have to choose upgrades for the pet such as: faster, stronger, better senses (wider visions, can tell enemy in bush, and can tell what direction the closest enemy is), or venomous (if a reptile-type pet). Along with the pet gaining a percentage of item effects. This would like healing if you use potion or +5% AD of each AD item you get. This idea seemed the best, but I kept thinking about it until I came to a whole new resolution today and is why I am making this forum.

TWO champions. One champion is the summoner and the other is the pet. This was an idea I had floating around wondering how it would work, mainly I thought "what if all the champions on a team had the same skins such as all 'Beach Party' or 'Pentakill' or 'Blood Moon.' All champions with those skins together will gain a slight boost like +2 AD. Minor but not required." The idea is that the two are separated and can each function on their own with other champions. Both will have their own full kit and abilities and different play styles, but if the two happen to be selected to be on the same team their passives activate and they both gain medium level increase in ability. I thought this is not only cool but would also be very unique and interesting for Riot to do if they ever chose to. Releasing both together and having them designed to work well as a duo would be awesome in my opinion.

What do you guys think of this concept?
