I dunno. The WTS is pretty contrarian in their own way; Rutherford started it, and they've never really shed that aspect of themselves.
Not to mention their passive/agressive attitude towards mainstream Christianity (plus a whole shit-ton of other reasons) would disincline them towards genuine, authentic modernization.
Don't make the mistake of thinking of the WTS as a progressive organization; it's ultraconservative and authoritarian to the core. Once a group has crossed that Rubicon, it's damn near impossible to reverse course.
