Here is a simple way, since you are receiving DICOM with JPEG 2000 encapsulated stream in it, simply pass the DICOM directly to GDCM to uncompress it. Then forward the decompressed DICOM to your regular DCMTK pipeline:

$ gdcmconv --raw input_jp2.dcm output_raw.dcm

GDCM by default is build with OpenJPEG 2.1.x.

Of course, if you are familiar with C++, you could directly call the C++ API directly, in particular have a look at the class gdcm::ImageChangeTransferSyntax.
