A six way collab is indeed interesting. I don't think I've ever come across such a thing before. Due to timezone differences though and people's work schedules, it might be more advantageous to split the collab up into smaller parts. I applaud the idea for sure, but if it's not feasible at the moment, you guys can easily go into pairs and collab like that while having the other potential members of the conversation responding by solo post in the IC.
Example:
@JulienJaden and
@OneWayOut collab and throw up a post.
@Garden Gnome and
@IcePezz read said post, then collab, and while providing their own responses to each other, they also respond to the previous collab of Julien and OneWay. Basically, everyone gets to get in on the interaction, but the posts are split up because it's just not feasible to have everyone collab in one humongous post if timezones and work will cause it to take a very long time.
Just my two cents of course lol.
EDIT - I should probably also mention that my own posts--combined with
@Rockette's in a collab--will be up today when I get off of work.
