D2X, 400mm f5.6 IFED AIS lens, Kenko 2x + 1.4x converters. Exposure 1/15 sec wide open at 5.6 ISO 400.

Don you nailed it so well.
Excellent.
May be first you want to add on the number of TCs before getting to higher focal length. BTW avoid cheaper manufacturer's 800mm or so prime lenses as the chromatic aberrations and poor quality glass rather significantly destroys the picture quality. Stay with Nikon, doesn't mater if it is manual. If you are buying on ebay, I can send you alert mail when I see some good deals out there.
