GEGL should support this, though there might be some parts of the code
that hard-codes the name of the output pad to "output", if there is it
should be fixed. For operations that need to output more data than 4
channels per pixel there is another option than outputing two separate
buffers though. The existing frequency domain processing ops for GEGL
from SOC (unmerged due to licensing issues). A custom 6 (or 8 for
RGBA) component babl format is used for buffers that store complex
numbers.
