Your suggestion :
data "geom from (select
SDO_CS.TRANSFORM(SDO_CS.VIEWPORT_TRANSFORM(<your geom column>, <SRID for
millimeters>), <SRID that you want as output>) as geom from <your table>)".
seems to work!
I did consider this option before, but I thought this would be not possible.
The documentation of SDO_CS.VIEWPORT_TRANSFORM talks about "optimized
rectangles" to be used for for this function. So, I thought polygons would not work.
