Why the hell would you do that?
You want to encourage people to take specialities over abilities. You want to promote people to deliberately limit themselves and take a more narrow focus of their ability instead of a broad one, because that makes them a more focussed character concept. The conscript in a prince's army should be encouraged to take a speciality in "Spears +1" over learning Melee 1, because he's a grunt who's been told to stand in line and stab the pointy end of his pole at the enemy when they come close. He's not got omni-skills with weapons.
The interaction of specialties and abilities are amazing as to what they tell you. And in fact I miss having oWoD-style attribute qualities as well because they do a lot of the same thing.
I don't want utterly ridiculous versatility in weapons to the point where Wuxia seems reasonable. A person should be able to beat the hyperversitile murder machine by using something they have put everything they could in.
This is Exalted, man. Playing Jason Bourne, omnicompetent murder machine is not only encouraged but expected. I'm not sure what the rest of your post is about because it's very confusing.
