Two things, there were a few Force Gifted characters through that era, not including simply Ben and Luke.
That is of course, unless you do not consider the New Jedi Order Books, and the after Star Wars: Return of the Jedi valid - because Mara Jade, the Emperor's hand, was force Gifted, as were several others whom Luke eventually took under his tutelage and trained to become Jedi.
But, for the most part, they were SO FEW AND FAR BETWEEN, that it would be very unlikely to encounter one, Luke was lucky, and he was the main character, and that gave him the advantage that I don't believe would be present in this Universe.
I was merely mentioning it - it sounds intriguing, but I'm kind of not into SW right now...
"... if it had to perish twice,
I think I know enough of hate
To say that for Destruction Ice is also great
And would suffice."
