I've been wanting to make a Skyrim mod for a while, but all the things I want to make seem to be really advanced, which is killing me.

The mod I most want to make would be a mod where once an NPC yields to you you can talk to them, and use your speech skill on them. You could intimidate them into giving you their items and rob them, after which they would run away, or you could persuade them into joining you, which would make them friendly to you. It always bugged me that NPC will surrender and beg for their life, but if you don't kill them then they will just attack you again 10 seconds later.
This of course needs to still work with stuff like the dungeon clearing system.

Is this something that is even remotely possible to be attempted by a novice, or generally in the game? I'm having a bit of trouble finding appropriate tutorials for very specific ideas like this.

I'd appreciate any advice people can give me.
