The SANE API only provides image data in SANE_Byte buffers. The GIMP
SANE plugin code would have to convert that to whatever format the GIMP
expects for 16-bit RGB (or grayscale).

FYI, the xscanimage GIMP plugin source bits haven't been touched for
over a decade (to cater to gimp-1.2). You may be facing somewhat of
an uphill battle there :-(
Hope this helps,
