I was trying to rig up a way to hang a bag in my keg for dry-hopping, and came up with this easy solution. Take a stainless hose clamp and tighten it around the inside of the poppet and stick the sting from the bag between them. Done and done. I'm sure i'm not the first to do this, but i thought i'd post it up in case someone else was looking for a fix that doesn't involve buying a new lid with a welded hook.
