I recently messed around with the team moves as well.  The problem is: we can't change the division names for the conferences.  If we had the ability to change Atlantic and Pacific division names, we could re-map the league almost any plausible way.  This is what I was doing to get a legend draft goin lately.   
- I added, Sonics and Hornets.
- I created Vegas Team and Vancouver Grizzlies.
- Hornets replaced the Bobcats.
- Timberwolves moved to the Bucks spot.  So they were in the east.
- Vancouver Grizzlies added to Southwest to Timberwolves(Bucks now) spot in the Northwest.
- Vegas Team took Memphis Grizzlies(Bucks now) spot in Southwest.
- Sonics took Sacramento Kings spot in Pacific.
Essentially I eliminated the Bucks and Kings.
I really feel like, in my perfect East/West world that OKC should basically be the border line for the split of the conferences.  I also think New Orleans should be in the east as well as Minnesota.  St. Louis should have a team in the central but there is no room for that.  The cities that have teams in the east are pretty dominant markets for the nba.
I think that's all I did, thanks for reading all of this for whoever did.
