Well we can leat them have camoufleur and we are now free to completely subvert camofleur to our hearts' content. I look at the -fleur and think that it should mean repurposing a piece of military hardware, like say a tank, by using it as a planter for flowers. At least in Bilby's Alternate Universe.
*facepalm* ...camoufleur is obviously the correct form. I think that is why I had little success finding citations. Here is a google books search ngram showing that camoufleur is by far the more prevalent spelling; in fact the number of instances of camOfleur is below the threshold needed to appear in the graph.
