Does qt5 work with touch and hw keyboard? If so I could be really interested here.

Aapo: Maybe you could try building hildon or qildon using this image. See how much fremantle stuff can be shoe-horned into jessie as opposed to trying to shove jessie into fremantle.

As its targeting a specific debian release, why not make it its own release instead of trying to keep 100% compatible with fremantle. We now have mce and bme replacements. Replacement apps in qt4 should be easy to port to qt5. microbe was based off sailfish-browser, so that can easily be changed to qt5. FMG, Pail and co. have been working on upstream kernel.

Maybe even swap in connman.
