Arghhhh!
The original idea was here altoghether with my answers:

Iam doing two force powers to add to the friendly force power menu, nothing more, nothing less.
Yes, it would be possible to add saber use...if I ever have enough time I may look at it but don't expect it in the two next weeks: I have too much to do. However, it would have to be placed in the friendly force power menu and it would be considered as a force power.
I'd also want the other NPCs to react appropriately (scream and run, draw weapons and charge, whatever.) and to gain some serious dark-side.
It is possible to make a script that will turn certain npcs hostile each time you draw the saber: like the people on Taris that are scared of you when you wear the sith Uniform. However, to scream, and change dialog, it would be necessary to add a few lines to every single dialog in the game (that is what they did on Taris). Changing a general reaction, wihtout dialog is feasible.
Add dark side points each time you use such a force power is easy: I just have to add a few lines to the code.
