Why would you want to expose these extra SAP profile details to the
Agent? The bluetoothd side should take care of all details like this
whenever possible. The only relevant data that needs to be transmitted
from the Agent to bluetoothd in this case is the ATR and bluetoothd can
then proceed with creating a proper SAP response packet based on that.

You'd need to define some sort of mapping table yourself. The list of
possible result codes is quite short (8 in SAP 1.1) so this shouldn't be
too hard. E.g. "Error, card not accessible" (0x02) could map to the
D-Bus error org.bluez.SapError.CardNotAccessible.
