Yes! I contacted that team, Cache Bucaneers about adopting all 8 of their caches last summer. There were one or two that were failing at that point, and figured since they hadn't been that active, they may want someone else to take these over. Basically, that would have loved for me to maintain their caches for them, but they refused to allow me to adopt them. I have chosen to maintain a couple of them on my own without their consent due to the great locations. Some of the others, unfortunately, have met their demise. Maybe another effort to contact them would work, since it's been awhile.
Here are a couple of links to more info,
