Just to be clear, I'm not in favor of depicting a pre-Episode IV Senator Leia Organa with any Force powers. I was just theorizing how powerful she might actually be based on what was established about her family and parentage and some dialogue from ROTJ.
Yeah, showing a teenage or prepubescent Leia with Force skills would create a minefield of continuity problems that could drag any such story down. Just depict her as a little girl or teenager with political savvy and idealism along the lines of her adoptive father and let the discovery of her Force powers and potential happen much later in the timeline.
Yea, but, I think Reverend
is right, you'd need to show her potential via insight/empathy/perceptive of integrity, kinda things, or else it would be "Outta nowhere" 20+ years down the line (Or as early as when it's revealed in Original Trilogy).

Where are we going? And why are we in this Handbasket?
