Whenever I watch something new I'm always keeping my eye out for little gems that might be reuseable as something in a different film, but realistically even if you found your perfect shot of your idea for a new style of clone warrior, the chances of then finding enough of those shots to be able to use in a meaningful way and make them mesh sufficiently would (sadly) I feel be impossible. Short of a director having made a film and recreated shots with something like this in mind it just seems like it would be too coincidental.

But if you were prepared to settle for human armoured clones (to hide specific features), and I would suggest looking at long running TV series just so there is more footage available, then it may be possible. This obviously wouldn't give you your ideal image of a clone, but it would allow the current Republic clone army to change to being just similarly armoured individuals recruited from the numerous planets in the Republic, which is in my oppinion an idea that is definitely worth pursuing.

As for suggestions the only series that springs to mind is Stargate Atlantis where the wraith warriors are all clones so look the same, are humanoid but clearly not human, and have a bad guy look to them. Whether there are shots which could be used for this purpose, or even look Star Warsy enough, I haven't a clue.
