Your trash location should be ~/.local/share/Trash. So, theoretically, you could run init 3, remove the Trash directory, and then create a symlink to a seperate location of your choice.
Hope that helps some,
EDIT - I just noticed that in order to pull this off, you would need to backup the contents within Trash first, then copy them over to the new location.
