It's not that much work actually

Jasper (the JPEG2000 decoder library used by jp2kdec) supports 12 bit
per color component. Adding support for this in GStreamer only requires
to add some enums to libgstvideo for the new formats, implement them in
all the functions that return the rowstride, component width, etc. and
then. Afterwards conversion from/to this formats should be added to
ffmpegcolorspace and jp2kdec should output with these caps if a 12bit
per component image is found.

If you want to try that feel free to ask further questions on IRC
(FreeNode, #gstreamer) or on this list.
