It's probably the most eccentric thing you'll hear for quite some time, but I always thought I'd like to have a good trustworthy team of investigators with me in the final minutes of my life, along with my family. They could park themselves on the periphery of the room with their equipment and my last contribution to the field would be letting them document my passing with perhaps some pre-assigned plans for what to attempt and where to concentrate their study. It would be something akin to donating my kidneys, just another last assist from the other side. I don't think this has been done at all, or if it has very rarely, because who ever thinks to have a team with equipment when you're passing? It's that rare moment when one goes from flesh and blood into the spiritual realm that you would have the greatest chance of proving the other side. I suppose when I get old and decrepid, I'll begin a good relationship with a team I like and trust who is in my town and have them on the ready in the future to get a call to rush to the hospital or my home on a moment's notice for the ultimate ghost hunt. Me!
