Putting bonus stream in front of the marathon is a structural nightmare. Think of what it does to presentation. The GDQ twitch stream already got people going "Huh, AGDQ started already?" when Studio was doing his showcase shows, 3 months before the event. Bonus stream starts, 90% of the audience is like "Wait AGDQ started?" And they get to witness the probably not fully tested stream setup, experience all of the technical difficulties, the not as serious runs, the lower production value, while people need to keep reminding everyone that, no, this isn't the main stream, this is just the bonus stream, that's why it's not perfect yet.
It's just not a good idea.
