How might one permanently change the key ability for a specific skill from a mental to physical stat?

How might one permanently change the key ability for a specific skill from a mental to a physical stat?

Specifically the Craft skill, and from INT to DEX, relating to a character that can carve whatever they see but doesn’t use intellect to do so as they are something of the classic Savant type which does not interface with the world through intellectual logic or thinking patterns.

I am ideally looking for a rule or mechanic that supports the concept, rather than just home-brewing something, if possible. If such a rule or mechanic doesn’t exist, then knowing that is helpful too. And something that can be taken at as low a level as possible, be it feat, trait, feature, item, or power.

I am aware of the Void Disciple ability of Void Release which swaps primary stats for all purposes temporarily, however, taking 10 levels of a prestige class for a 3/d ability is very suboptimal, and does not meet my requirements. The Variant rule for alternate ability skill checks is DM dependent, therefore it may not work when moving the character between different groups and thus is likewise not what I’m looking for.
