Using a pre-built MTK6589/8389 kernel in a custom (Lollipop) ROM

I've got an old Lenovo S6000 which, like every other Mediatek device, has incomplete source code for the drivers and the kernel. As a small project, I would like to try and get Android Lollipop up and running to an extent where:

• the system boots to the GUI;


• the Wi-Fi works;


• and the touchscreen works.

just to start off.

The device currently is rooted, with ClockworkMod recovery installed, and I can create Android back-ups of the system. Could I potentially take the kernel and the proprietary blobs and build them in to a CyanogenMod 12 update? Or would the kernel have to be patched to support the new features in Lollipop (the current OS running on the device is Android 4.2.2, and there have been no other working attempts to create a custom ROM for the device)?

Thanks,
George
