Could we switch Killers in 2v8 lobby please?

Hi. I understand why you can't switch killers once you are in a 1v4 lobby. Cuz players would switch to the strongest Killers whenever they saw a full medkit or flashlight lobby, etc. But we don't have to worry about that in 2v8. So why are we still locked onto a killer?

I feel like we should be able to switch characters even after we've found a lobby. Especially since queue times for Killer are still really long. Maybe after waiting 30 minutes I changed my mind and want to play someone else!

What do you guys think?
