Alternatively, you can make those properties bindable. This will cause the compiler to automatically generate the corresponding getter and setter and the interface will be implemented.
However, your example will never work as it is. AS3 currently does not allow implementation signatures to differ at all from the interface, even if they are compatible. I'm hoping that will be "fixed" in a future release.
