Whether it makes business sense for them or not, I would definitely be interested if they did. I have bought Marlins and Rossi's and, while they are great, it would be interesting to see a Ruger variant. Years ago, I wasn't a huge fan of Ruger anything. It seems like, over the last few years, that most of my new acquisitions have been Rugers.
I disagree that only cowboy action shooters or old timers like them. I have never done any cowboy action shooting, I don't hunt anymore and I am not quite an old timer but they are one of my favorite firearms.
