S4 Features for CM12 topic

We know, of course, the original android is cool, and the CyanogenMod (or AOSPA, AOKP) is very cool. We can't have some features of Galaxy S4 (Touchwiz) in CM12. For exempla the camera, toolbox, USPM (S5 feature ported to S4 in some roms), Mult-windows and more. Is possible port these features for CM12 ?

Sorry for my bad english :cyclops:
