the consensus that now exists on the desirability of finding ways of defining all of the base units of the SI in terms of fundamental physical constants so that they are universal, permanent and invariant in time.

The July/August 2011 edition of IEEE Potentials contains a paper with the title, A Methodology to Define Physical Constants Using Mathematical Constants.
The concept described in the paper identifies a fundamentally different way to apply mathematics to physical law. Those with IEEE membership or associated with an institution that has a membership can read/download the paper from: A Methodology to Define Physical Constants
The paper is on the second page of the Contents.
For those that do not have an IEEE membership, the postprint can be read/downloaded from: Methodology
The IEEE publication has a classic image of Euclid on the first page of the article, which IEEE slightly altered; the technical material is identical.
The concept uses the relationships of a fundamental physical law and basic geometry to define two basic units of measure.
