Help Finding A casting class for 3.5

[Mizter0oz]

I currently have a character; He is a spell sword 2 Fighter, 4 Sorcerer, 1 spellsword and 5 abjurant Champion. However I just realized that at level 20 he will never get 9th level spells (this is important for epic progression).

I was wondering if anyone knew of a full casting class that has mid BAB.
-The only one I can find is Unseen seer.

Home-brew classes are welcome pathfinder or anything published is better and WOTC 3.5 is desired.

Thank you,

Dragonslayer and Bladesinger are 1 level dips for full BAB and casting.

Sacred Exorcist has full casting and medium BAB.

This is a standard gish build called the Sorcadin:
Paladin 2/ Sorcerer 4/ Spellsword 1/ Abjurant Champion 5/ Sacred Exorcist 8

Mid Bab full arcane casters that might fit into your build (I've excluded some that can progress acrane, but require some divine or other casting):

Auspician - Faiths and Patheons
Heartwarder - Faiths and Patheons
Evereskan Tomb Guardian - Player's Guide to Faerun
Harper Paragon - Player's guide to Faerun
Sacred Exorcist - Complete Divine
Unseen Seer - Complete Mage
Knight of Thorn - Dragonlance Campaign Setting
Master of the Yuirwood - Unapproachable East
Tainted Sorcerer - Unearthed Arcana
Ruathar - Races of the Wild
Spellwarp Sniper - Complete Scoundrel
Zhentarim Skymage - Lords of Darkness
Spell Singer - Races of Faerun

Personally I think Knight of Thorns fits's your build stub pretty well and has pretty easy reqs if setting specific stuff is allowed.
