I'm almost finished on my current KoTOR playthrough, and I will want them done before I start another TSL playthrough. So hopefully I'll be able to iron out any issues and convert everything to TSL very soon. Of course not everything will be replaced, such as a few of the new melee weapons in TSL like the staves, plasma torch, and axes. Maybe in a future update, but not this month anyway. Also, I would not have my hopes up for any of the low priority stuff that I have listed at the start of the thread. I don't think the effort is really worth it, for various reasons.
So yes, once everything is finished, it will be released in a pack for each game.
