This is a great idea. First we all know that we have communication problem and this idea is based on this problem.
we have to understand that the knowledge are not the words,
the words are about the knowledge.
Who cannot understand this, will use the words to suppress the other.
Who can understand this will use the words to share and increase the knowledge,
and there will no communication possiblity between these two kinds of people.
One is NEGOtiating, the other one trying to COMMUNicate.
I think the basic problem of communication relay on this problem.
The only solution to get of this problem is education.
Education with words and more than this, education with other languages like geometry, music (notes), all kinds of arts. (different senses or/and different languages)
This may not be appear like a direct idea of your proposal but this may open a wider and deeper perspective to the problem of communication.
