Two other areas worth exploring with your existing 200mm lens is using a combo of either/together
1. a teleconverter 1.4x, 1.7x, 2.0x - downside is softer images and reduction in max aperture the greater the magnification used
2. In camera image area reduction by 1.3x (18x12) - giving a further 1.3x optical reach on top of the DX 1.5x (24x16) giving equivalent of using a 390mm lens.
I don't think a teleconverter would provide good resolution on my 55-200. Also the 1.3x optical reach you mentioned I believe is actually a digital zoom which can be achieved with a crop during post processing.
