Yes, there are a number of papers dealing with DNA studies on conidae. Much of the work has been carried out by Alan Kohn, Thomas Duda, Palumbi and others, and also Rafael Zardoya and Regina Cunha have examined DNA of Cape Verde cones and are involved in more in depth studies of this kind. I have references if anyone is interested.
