I don't understand what you're asking. BUT, you don't need 120 of a skill... ever for BODs. Sure, it helps for crafting the exceptional items, but 100 or 120 seems to give the same mix of deeds. Having 120 of the skill doesn't enable anything. Having 100 does though I think (not sure, I have had 100 or better tailor and smith on my primary crafter for roughly 15 years)
Next, you only need 0.1 to get a deed... granted you will only get normal material of normal quality, but this is generally fine to bribe up to something useful, or cycle over to the guy with 100+ of the skill and do the turn in.
I have NO idea what you're getting at about using soulstones and 120 tailor/smith - I have 1 character with 120 of each, and it works great that way.
