Of course most of us are aware of the idea of using a longer lens hood on a small sensor camera - the well known use of the 17-55 hood (EW83J) on the 17-40 for example.
However, what about full frame? Most people would simply say that the standard hood for EF lenses is designed for full-frame, and leave it at that. Since I had some hoods kicking around from my small-sensor days, I decided to experiment with a few with my 5D...
First of all, I already knew that I can use ET-65 instead of ES-65 on my 50 F1.8 mk 1 - that worked on film. There is a practical downside though, in that the hood can't be reversed on the lens on the camera because it is in fact longer than the lens itself.
Next lens up is the 17-40. This is where I really wanted to improve things over the EW83E, which I find impractical. It is too big to conveniently carry around, and certainly not feasible to reverse it on the lens.When I first got the 17-40, the crop-sensor hood du jour was the EW83DII, meant for the 24 F1.4L. On the 5D this gave visible vignetting, but only very slight (worst case 30px). I'm not the first person to take a file to this hood, and surprisingly little material needs to come off to make it work without vignetting.

The other hood I had for the 17-40 was the EW83J. Obviously no use on the 17-40 on full frame, but out of curiosity I popped it onto the 24-105 F4L IS and gave it a try. No vignetting at all, and it is a good 15mm (3/5") deeper than the stock EW83H. This requires no modification at all on the 5D.
To conclude, the possibility of improved hoods isn't limited to cropped sensor bodies (where you could argue that it would be appropriate hood, rather than improved), but there's room for improvement in full-frame also. Another option to look at would be the new EW83K (24 F1.4L II).
