Have you considered the possibility of using Mixer for your streaming channel ? Even though it`s currently the youngest streaming competitor out there going up against the likes of Youtube and Twitch it`s actually useful if your wanting to go in the direction of multiplayer co streaming. Can have up to four different streamers all streaming a multiplayer game together on one page and I think that would be quite a catch in terms of reaching out and pulling in new people.

Plus with Mixer it`s not that much more of a complicated process since any users watching the streams can just swap between one another with ease. I`ve used it myself once or twice and have found also that the chat rooms in Mixer are a lot more open and interactive than the ones on Twitch. Just a suggestion of course but if your going with Twitch I`m more than happy to get on board with it.
