How about getting one of those Soda Caddy hats, replacing the can holders with shockmounts, sticking a couple of mics in and plonking it on someone's head!?
I'm not EVEN laughing at this. (Smiling though ) If I thought i could get away with it, an 'XY' Bowtie would be the perfect spot. (Maybe even a bit lower?) Great isolation from the room, down nice and close in, arms and sticks not whacking into the mics. (Except for the inevitable grunting and snorting we humans do without knowing it.)
