Yes, it's definitely possible - the issue is really the design costs. Especially a full metal device I might sell a few hundred of at the moment. The cost of designing and certifying an aerial for Bluetooth and GPS in a metal case is going to be tens of thousands of pounds - and per-device for 100 devices it's just not going to be something most people are willing to pay for :(
