I don't know because, as far as I'm aware, they've never said one way or the other. Maybe they have said something somewhere but I wouldn't even know how to find it. Resurrection seems pretty implausible and they've perhaps not discussed it just because it doesn't seem technically possible at the moment, if ever.
However we do know what they think about scientists creating life because they said so.
The question is, even if the Watchtower allowed for the possibility of resurrection, and said so in their publications, would you accept that's what they really think? Or would it be another, "they don't really mean what they say because I know their doctrines better than they do" scenario.
On a related issue I think JW theology actually lends itself quite well to adaption to transhumanist notions of technological salvation. David Gobel of the Methuselah Foundation is reportedly a JW and Aubrey de Grey has had some contact with JWs. They are both interested in technical solutions to aging and death including cryonics. I have sometimes wondered if JWs could morph into a transhumanist cult at some stage. That would make for a good novel!
