Division of the groups
Knowing who has been "notified" would be helpful. And knowing what skills people bring to the table would be helpful as well.
Ash is a computer hacker and cyber witch; and given his connection to the Cyberpapacy would probably make sense for Copenhagen. With that being said, there is a decent amount of overlap between him and Ballon Rouge, so we might want to split them between the teams.
It also seems like Case and Dr. Fleming might have some overlap as well (as I'm getting psychic vibes from her), so we might want to split them up too.
I don't know what Will can do, but he seems close to Dr. Flemming, so probably makes sense to keep them together.
It seems like sending Solar Shield to Ethopia makes a lot of sense considering that mission sounds like it's going to be heading into the Nile Empire which is his native cosm.
Johnny is obviously the muscle as an electric samurai along with Solar Shield. I get the feeling Antoine might be as well, but I'm not quite sure.
And I can honestly say I have no clue what Void is or can do (which I suppose is the point :p).
So given all of that, as well as who was on the previous mission, my recommendation would be something like:
Copenhagen:
Case
Johnny
Ash
Void
Antoine LeCoeur
Ethiopia:
Ballon Rouge
Dr. Flemming
Will Blackwell
Solar Shield
