I think it could certainly work depending on like personality which I'd trust your opinion on much more than mine. My biggest concern would be them stuck between a turf war a chocolate on one side and pikes on the other. I would probably acclimate them in quarantine or divided for some peace of mind, and keep the divider handy. That's a lot of space for them to work with and I can't imagine the group of 10 allowing one to be picked off unless one of the two aforementioned come at them maliciously but that's usually clear as day. My chocolates are big wimps, but like temperament is something I haven't experienced yet. My opinion would officially be if you have the pikes and choco comm'd right now and you think it will work out, it probably will. I'd give them space in quarantine probably, if your chocolates eat like mine do I wouldn't want to try confirming eating with that level of competition.
