I'll draw a rectangle at the center of the screen, and let the user scan the QR code. QR code outside the rectangle won't be recognized. Possible to do?

We are using ZBar for our Plugins API, QR Barcode detection so what you could do is change the code there in a way that would allow you to have the functionality you desire. Maybe this article could provide you with some further insights http://zbar.sourceforge.net/.
As an alternative, you could use another library for reading bar codes and integrate it with Wikitude SDK.
