What are the odds that some class, say Culinarian, gets a better version of Steady Hand 2 as their lvl 60 skill?

Lets say Steady Hand III, increases success rate by 40%?

Think that could happen? Something to remove some of the incessant RNG from crafting?
Could also see a stronger version of Byregot's, say +30% per IQ stack?

What do you guys hope to see in the lvl 60 skills?
