Judging from the newspaper in the background, I'd say that we might be having a bit of a language barrier issue, although OP is certainly doing better at English than I would at an Asian language. That looks like a Google translate issue in the title, mixed with an auto-incorrect on "ahout". I hope he got a really good deal on that lid.
Im sure plenty of people here can turn that into a Stormtrooper.
I'm happy you paid a very low price for it, but what is it made out of? Depending on the material, you may not be able to widen the helmet much. Considering how thin the helmet looks, I'm thinking that it would look silly to have it displayed as a prop replica. Perhaps have some fun with it and make it into something different. I have no idea what though...
