Is this (hypothetically) too toxic?

Let's say, hypothetically of course, that I wanted to learn Shaco Jungle for this season. To do so I join draft pick, and most games I end up in my secondary role because jungle is hard to get.

Now suppose my pick intent says Shaco, and somebody on my team bans Shaco. Is it (hypothetically) wrong to instead lock AD-offtank Swain Jungle and state this clearly in chat in order to make someone jump queue? The strategy worked perfectly to my (hypothetical, not real) expectations, and I was (would be, hypothetically) ready to play AD-offtank Swain Jungle even if the banner hadn't (hypothetically of course) repented his crimes and jumped queue.

I feel bad for those hypothetical souls who have to jump queue for misunderstandings like this, but I also feel bad for players who have their champs banned by teammates. I normally don't care if my champs are banned. The only hypothetical exception for this is when I am first pick, and I only want to play Shaco, and someone bans Shaco.

P.S. Hypothetically: If Teambuilder were re-introduced some day, wouldn't this problem be solved?
