Wha gwan Dave? It's been a while!
I don't do multi-staff - I don't even do doubles - but I had an idea which seems to make sense. I dunno maybe it's lame, it's not particularly tech but I think it would look well good, and is quite down with your style of tings:
Basically transverse plane elbow locks and spins on both arms with neck lock and spin in the middle. I was initially thinking they'd all start parallel but actually the neck lock would be at a wider angle wouldn't it? Maybe not... Anyway start off vaguely parallel, quarter turn the staffs to lock on the other side (so the neck one would go in the opposite direction to the others, right?) to finish all parallel again. Keeping the elbow ones parallel, do an elbow spin and neck spin at the same time (opposite direction). This should mean that if you get the timing right the staff shouldn't collide.
That might not work at all. Sitting here all staffless, trying to work out whether they'd collide or not, or whether you could do it with them all spinning parallel in the same direction, but I don't think so unless you had impossibly short staffs.
I think one's enough for me.
