A one shot ranged melee ability... Great idea. While we're at it, let's make warlocks one shot melee as well, that can't POSSIBLY go bad. Titans have to decide risk vs. reward for their melee ability to proc. They can't just walk up and punch you, they have to get a sprint going and close the distance. Any close range weapon becomes your best friend in that instance. You're not a "noob" for using a shotgun despite what the horrible players say, so whip it out and take the titan down before they close the gap. As far as supers are concerned, just no. I'm not even going to explain it, I'm just saying no. Now, what would REALLY be interesting is if they added an exotic that causes Tether to do what you mentioned. It would suddenly give people another option than Orpheus Rigs for an exotic piece.
