Yes, the Thought Bomb from the Darth Bane Novel is a good idea. There should be dozens of new Force Powers. Get rid of the tired ones like Force Shield, Force Scream, Force Armor all those pansy weak light side powers that none of us really play with Dark or Light. And give the main character the ability to sense Force sensitives and convert them to Jedi! Now that is a cool.
Would I pay for a re-released TSL, with all cut content restored, and all bugs fully worked out? No.
For them to do that, it would be a full game, which they'd charge full price for.
Would I like them to release it as an expansion? No.
That would be them still making money out of us for their bad decisions.
Would I download it as a major game update that was free because they realised how badly they cocked up because of haste? That would be an infatigable yes.
