Practice Tool Enhancement

So basically I would like to ask would it be possible for the practice tool to add the option to have one other player on the enemy team so you can test combos out on each other? I believe this would be a great idea to implement reason being that there are times when champs like Yasuo are always almost banned and even though you practice combos in the practice tool you actually get better with doing it against other people or bots. But I personally don't find bots to be that helpful because when you play ranked you're not going up against bots you are going up against people. And I know you could just go in a custom game but I feel as if through you being in a practice you get to do the things the practice tool was meant for which is testing out builds and combos without having to worry about CD or farming because that takes a lot of time to do. I would say have it so only one player can join your team. So please comment on what you think pertaining to this. Or how this could be better.
