Answer 1

You definitely are able to sign an already signed apk multiple times using different keys:

Note that you can sign an APK multiple times with different keys.

E.g. I accomplished to sign a Debug-Apk with the release key so that I was able to test upgrades of released versions. Also, I was able to sign an already released apk with the debug key for reproducing bugs.

This is what you should do

1. Rename the .apk file to .zip
2. Unpack the .zip file and remove the META-INF folder
3. Zip the folder again and rename it to .apk
4. Sign the apk:

    jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 \
              -keystore my-release-key.keystore my_application.apk alias_name

For the debug key, the alias should be androiddebugkey and the password android. The debug keystore is per default $HOME/.android/debug.keystore. See also Signing in Debug Mode.
