This is perhaps a borderline modification since I have not designed, made or modified any hardware. The only thing I did was I used a product on lens models for which it was not developed, to a good effect.
The 4th Generation Design company market their CR-80 replacement foot for Canon 800mm f/5.6, and on that lens the foot has worked great for me, both for hand-held and pod mounted duty. http://stores.4gdphoto.com/cr-80-replacenent-lens-foot/
However, a couple of years ago I was experimenting a bit with different aftermarket feet for all of my MkII long lenses, and I found that CR-80 worked very nicely on 300 f/2.8 IS MkII as well as 200-400L, and most probably it would work equally well on 400 DO MkII.
The foot is plenty long, comfortable in hand when supporting the lens & shooting, it also gives sufficient finger clearance when used as a lens carrying handle, and it doesn\'t interfere with the hood reverse mount. Last but not least, the foot mounting flange with its bolts fits perfectly on all of those lenses.
