[Q] Newer camera app of 6+ working on 6?

I have a honor 6 and noticed in a review of the honor 6+ that it has a newer camera app with super night mode. i would like to try to install that app on my honor 6. it has the same OS (4.2.2, emui 3.0) so it maybe works on the 6.

what do you think?
can anybody extract the camera apk and send it to me? would be great!
