Yes; the caveat is that it's really only practical to have one card out on extenders at a time (and I have only one hex extender in any case). So you have to be a little choosy about what you want to capture/see. Some things can be plucked from the backplane, but I like to avoid sliding too many probe connectors onto the backplane pins unless I really have to, in order to avoid perturbing the 45-year-old wraps. --FritzM.
