I highly doubt that, if any toy company took over the Star Wars license and started a whole new toy line from scratch, that the first wave would be nothing but OT figures. In fact, I think PT figures would likely dominate the first few waves.

But since that's not the discussion here, these are my picks of the "first 12" ANH figures:

1. Boba Fett (we are living in a post-SE world, like it or not)
2. Darth Vader
3. Luke Farmboy
4. Han Solo
5. Princess Leia
6. Stormtrooper
7. Sandtrooper
8. Chewbacca
9. C-3PO
10. R2-D2
11. Luke X-Wing Pilot
12. Ben Kenobi
