Honestly, I think you can rarely make a convincing case based on technical merit or productivity promises alone. There are often good reasons to be conservative about technology choices. I would try it from a different angle. If the organization wants people who are able to come up with fresh ideas, these will not be the same people who are content with using only very mature technologies. If the organization wants to cultivate an innovation mindset and be attractive for innovative people there needs to be space for experimentation. Who knows what comes of it. Maybe that's the point where you get fired. If you were hired by an insurance company to maintain their 2002 style J2EE monster that's what's going to happen.
