From your OP it sounds like you're planning to have progression depend on material, while weapon style is mostly aesthetic. If you're planning on tweaking a few editor values though, I think you could accomplish a great deal of what Jeffman12 is asking, at least as far as damage and attack speed go. Some hidden perks could also possibly be used to achieve things like better blocking and better stealth (they'd be very similar to that Dwemer armor/smithing quest reward perk.) I'd really like to see the weapon style tuned to play style rather than skill level, it would add a tremendous amount of variety, though it would be sort of a nightmare to balance with so many possible combinations.
That's the plan, depending on which values are in the creation kit. Another benefit to adding weapon styles via books is the books can give the player a brief overview of that style's particular bonuses since the UI leaves that information out in Skyrim.

That sounds like an excellent solution.
Perhaps even a book for each specific weapon in some of the more exotic cases, so learning the entire Dremora or Dwemer style would require a larger investment of time or resources. I think I'd find such a scavenger hunt rather satisfying!
A further alternative might be the ability to learn certain smithing styles from a trainer of the appropriate culture in exchange for gold or a simple quest. Orcish weapons and armour from the Blacksmith in Markarth or one of the Orc encampments.
Well, the blacksmith's possession of and authoring the book may be close-enough to learning from them.

I may, for the more exotic styles break them-up like you suggest and have one weapon learned at a time. Would be rewarding especially for styles like Orcish & Dwemer.
