Integrating Sensor Fusion app into UE4 ?

I found this app https://play.google.com/store/apps/details?id=org.hitlabnz.sensor_fusion_demo and when I tried it, it did tracking spot on.

I wonder if Epic thinks it would benefit tracking for Google Cardboard and would integrate it into UE4, since the license allows for it.

The paper can be found here: http://my-it.at/media/MasterThesis-Pacha.pdf
And there is source code for Android on bitbucket : https://bitbucket.org/apacha/sensor-fusion-demo

Cool stuff
