Mod Idea - Favored Soul as a Sorc Kit

Heya,

Since it's now possible to create kits for the sorcerer AND it is also possible to limit what spells are available to what class, I'm pondering creating a Sorcerer Kit called the "favored soul".

Here's how I would pull it off :

- Create a "Favored Soul" Sorcerer kit :
Have them get THACO progression equal to clerics rather than equal to wizards
Have them use d8 as their hit dice
Have them be able to use any "medium or lesser armor" (IE : Everything but Plate / Fullplate)
Have them be able to use any shield.
Have them be able to use any weapon.
Have them get specific bonuses at level 1, 4 and 12 depending on their alignment (IE : Depending on their deity... would probably use the same deity as the cleric, IE : Lothander for good FS, Helm for neutral FS & Talos for Evil FS)

- Prevent the favored Soul kit from getting level 8 & 9 spells. Instead, alter their spell progression to a cleric spell progression.
- Duplicate every Cleric spell into Wizard spells.
- Prevent all but the favored soul to be able to pick those "cleric" spells
- Prevent Favored Soul to be able to pick wizard spells.
- Duplicate every Cleric HLA into Favored Soul HLA.

Anyone think this could be possible ?

The part I'm the most worried about is the "prevent x to pick y spells", I'm not sure how the engine does that.
Does it simply hides those spells from the available choice - best option - or does it greys spells (worst option : would make it impossible) ?
