It is possible to do with InteractionRequests, but with the current code base you would need to write your own custom behavior to do the presentation part as a windowless border and handle the background overlay as well. The built in one in WPF just uses a Window to create the dialog, thus the standard frame. I will put an issue in for this under our new code base at http://github.com/prismlibrary because it is a common request and hopefully we can fit it into a future release.
