I am a great believer in pilots being able to hand fly and this is what I do with guys once they get comfortable with jet ( about 200hrs) I then introduce raw data, ILS, then Flying vectors at night and then take the map modes off (all over a few months) most guys that fly with me can now fly raw data hand flown dme arcs to vor/ils arrivals all with just HSI! no map mode on at all and it seems to really widen their situational awareness as well.
All these guys are 200 hr guys initially and it can be taught but it needs captains who are willing to let guys do it as you may have to tell them to go around or take the controls back off of them. I have never set off the OFDM and have seen some pretty atrocious approaches but i would rather see them in a controlled enviroment than on a dark stormy night!!
If you can't fly a modern jet like it was piston twin should you really be in the seat anyway!
Well I hope your employer knows that you are using line flying for your private training method?
