Hey UGLYKID
It's not really my thing, but I actually talked a while back with a Funeral Home Director was very interested in if anyone had actually ever considered, or might have converted a PT into a Hearse, or at least a transport vehicle to bring recently departed back to the Funeral Home. I did some research on converted PT's, and still have a couple of photo's left over in my extensive archives of strange, and unique Cruisers. Please note, the first three are actual working Hearses, while the last two are themed PT's, and not actual working vehicles.
Yoy might also check out these two links for two other Death Themed PT's:

Hope you find the inspiration your looking for!
