[Q] Note 4 ~ Android 5.0 ~ Touchwiz topic

Okay first of all, I have only made one ROM ever, so I am not the brightest on this subject. My question though is for a Dev that is fairly smart. Would it be possible for those itching to have lollipop on their Note 4, but who don't want to lose Touchwiz features, to install the international Note 3 5.0 ROM on their Note 4 if a Dev would port it. If its possible why hasn't some talented dev( because there are several here) ported it yet. I know the structure would be a little different, but I'm thinking it would be entirely possible to port it with some tinkering. Just let me know if I am way off base or if this would be something to really look at.
