Except for the fact it's unbalanced. As it stands, KotOR's d20 system needs a major overhaul, failing which, an alternative system should be provided. No challenge = No fun.
However, the "let's everyone stand on this side of the line" FF system would be a terrible idea.

Well, maybe if they actually made it TURN BASED LIKE IT'S SUPPOSED TO BE AND DIDN'T MAKE LIGHTSABERS JUST +3 SWORDS AND HAVE EVEN GODDAMN GAFFI STICKS BLOCK THEM OR MAKE RANGED WEAPONS THE EQUIVILENT OF THROWING ROCKS AT AN ONCOMING TRAIN then it would work.
Just say "No" to pause and play.
