Here is a very, very easy custom. A friend gave me the parts to do this and said he'd buy me a bonus SAGA2 Sandtrooper and a few other figures if I made something, so here's what I came up with.
SANDTROOPER COMMANDER

head - SAGA2 Sandtrooper
pauldron - SAGA2 Sandtrooper
body - Evolutions Clone
kama - Evolutions Clone
Very easy. The only painting I did was smear some yellow brown paint on the plastic in some areas, then rub it off. I kind of stained it, which seems to match Hasbro's weathering anyway on most figures lately.
