RE: Would this work?
It's been done by lots of folks.
First off though you need to do some more research on cutting away the control surfaces and how to install hinges. And forget the copper wire for connecting the servos to the surfaces. In fact your last post suggests that you need to do a lot more Search functions on such things as "how to hinge" and "control installations". There's been a number of such threads in the past that can guide you on these basics. After you read a few of them if you still have questions come on back.
I'd also suggest that a brushed 380 can motor is going to be marginal power for one of the 3 foot wingspan foamies. There are cheap brushless combination packs of motor and ESC available from such places as Hobby King that would produce a far higher chance of success.
