Scanner profiles only work in one direction, from the input data (RGB) to the Profile Connection

There are ways of using an input profile for output space if you really want to.
Argyll's icclink for instance, has a mode (-G) that creates the PCS to device
conversion by inverting the A2B table, so using this you could create a
device link with an input profile as the output space.
