I carry an extra treking pole (A Titanium Goat adjustable CF pole at 3.4oz) in addition to the 2 I hike with, an ultrapod I (1.7oz) and 2 velcro straps (the Ultrapod already has one attached to one of the legs). I use the velcro to strap the 3 trekking poles to the ultra pod legs and set my Camera or Camcorder on the Ultrapod. If it's windy, I'll hang stuff sacks underneath to add some weight (though I've never tried this in heavy wind). Due to the flimsiness of the UL trek poles, I use a timer on my camera since touching it causes some shaking. However, I've never had a camera that weighted 37oz on it, so I can't comment on how well it will work. I think the key will be how rigid the trek poles are.
When totaled up, I carry an extra 5.1oz of gear to make a tripod. Once, I was glad to have the 3rd pole as one of my poles broke on me during a trip so it was nice to have a backup. Instead of a 3rd pole, you could look for a suitable length stick on the trail and try using that.
