I too had this idea, so I sent an email off to Gossamer Gear. Within a few hours, I got a reply saying the following:
"if you have the LT4’s with the strap option we’ll soon have a camera mount option/attachment for them. Basically you’ll remove the strap and screw in the mount."
Leki has a feature like this as well.
I didn't get the strap option myself, so I might send my non-strap ones in and do a swap.
I could just try putting a bolt into the top of one of the handles. If I can prop up my pole by lashing it on to my bag or nearby rocks, etc.—and have it stay up—it would be a pretty light camera support option; it would only necessitate the marginal cost of one bolt and some of my time/frustration.
