Trade skill changes

[disenchant]

I wasn't too sure where to post this so I did so here.
I was wondering if it would be possible to change certain trade skill recipes in order for them to make sense and allow them to become useful.

Black Smithing:
Silvered weapons require a 49th level enchanting spell and a jacinth to produce Enchanted large brick of ore (the product is equal to a magic fine steel weapon) making the entire line counterproductive.
Maybe require small brick of high quality ore instead in the current recipes?

Ornate Chain Armor is only 1 armor class better than banded yet requires high quality ore, making this item obsolete and too costly. Perhaps this could use medium quality ores instead.

Fletching:
Crafted bows lack a superior quality over dropped versions preventing a viable resale due to their high production cost. Perhaps the cost or high end crafted bows could be modified to create a balance.
