Gimp simply can't deal with 16bpp, even internally.  So it'd have to
chop the channels down when importing.  This problem is why the filmgimp
fork was created years ago.

Not sure what this has to do with the OP's question.  He wants to be
able to display the data on one hand, and keep it natively 16bpp on the
other hand (for manipulation). Thus he needs a 16bpp internal
representation, regardless of the display.  How gimp performs this
conversion and subsequent data loss is irrelevant.
