Hmm... I've given this some thought, and there's not much I would change (at least as far as the cast is concerned). I would like to see a more cerebral plot, more like the plot to The Motion Picture, but maybe not with as plodding of a pace. I would like to see Star Trek: Planet of Titans adapted with the new crew, or if we were going full reboot, completely wiping the slate clean, an adaptation of Phase II's Kitumba. But I'm absolutely positive TNG and DS9 lovers would shit their pants over such a reimagining of the Klingon Empire.
