My guess is that this should probably be possible given separate threads for each of the viewers frame loops i.e. run them all in a background thread. Sharing of images is possible by using a frame buffer copy to osg::Image, or just having multiple FBO's all within one graphics context. If you can have the frames all done synchronously then perhaps you could have one frame loop and just disable the cameras that you don't need updating on each frame, i.e. main viewer runs at 60Hz, and the other RTT cameras run at 20Hrz so get update on frame in 3.
