I'd ask what sort of bearing we were talking about, here :) Not sure how many babies I can bear at any one time :)
I've tried this sort of thing with people before and it often felt like a tug of war. I'd come up with something and then the other person would disregard it or want to express their own idea. I guess it's a bit different in that it's a continual chain, but maybe that makes the chaos more prevelant. I guess I'd be interested in knowing about how strong the enforcement to keep on task would be, while at the same time how creative can one get, given the context of the setting, that might still ruin it for everyone just because it may alter the tone too much?
