I notice there are no rays in that list
You'd rather have all that? That's pretty hard if you're a focused diviner.I'd rather have:
1. Grease x2, Mage Armor
2. Glitterdust x2, Web
3. Stinking Cloud, Sleet Storm, Summon Monster III
4. Black Tentacles, Dimension Door, Solid Fog
5. Cloudkill, Major Creation, Teleport
6. Acid Fog, Wall of Iron, Summon Monster VI
7. Plane Shift, Greater Teleport x2
8. Maze, Quickened Dimension Door, Greater Plane Shift
9. Gate x3
Note that this is all Core. Some stuff could be subbed out for better outside Core, I'm sure, such as Benign Transposition for one Grease, Dimension Step for Summon Monster III, or Freezing Fog for Acid Fog.

I don't ever use it, but I do like having a lot of true strike, true casting, and quickened versions of these in those extra slots.. makes your ray attacks (if you use them) and SR yes spells better.
Also, on the Spontaneous Divination thing: I don't think this will work as you believe. Your focused specialist slots must still be filled with divination spells. Being able to cast these spontaneously in exchange for another, prepared spell, nets you next to nothing. In fact, Spontaneous Divination is about the single worst ACF you could shoot for with a Focused Diviner, if I understand correctly how this works.
