I don't think a force feedback would by you much if anything. The point
where the clutch engages/disengages doesn't seem to translate into a
significant actuator force. If you want a feedback, you probably want
something related to the torque or rotational speed difference between
clutch input and output. This could also be a starting point for a semi
automatic shift.
