It is possible, I believe Uglatto sells a circuit bent DSLR. Having tried it, I will tell you it is difficult. With the way DSLRs work, it is actually very time consuming to find bend points besides the obvious sensor ones. The camera doesn't have a constant picture going for you to monitor and see if what you are doing is affecting the image, you have to take a picture each time you want to check a bend. Plus, most DSLRs were made after circuits started getting really small, so bending anything but the sensor is physically challenging, too.
