Another actress suggested by Dan Aykroyd back in 2009, and another one with experience with the paranormal: Charmed's Alyssa Milano. You can take the suggestion of her inclusion with a grain of salt, same as with Dushku, but there is a link to the Ghostbusters franchise already established with Milano: she actually appeared in 2009's Ghostbusters video game. Since 2013 she has been starring in Mistresses on ABC.
