Jedrek, I sent you my Skype contact info.
When you really think of it, the Republic Senate isn't going to be quite so difficult to simulate - we could establish every planet as a "County" and simply replace the title "Count" with "Senator"; then script events that simply allow every Senator a vote, which is more or less already done with Electoral HRE.
Just a thought - while we could go the one planet = one county route and just add more cities/castles/temples to show significance, this might underplay the importance of planets like Coruscant or Tatooine. I've edited my map files again to show what could be done with the most significant planets. As planets decrease in significance, they could have less provinces, so we could have 1, 2, 4 or 5 provinces per planet dependent on how important they are in the SW universe. I also coloured the reflections file black here to make space look more pretty.
