I read the Wikipedia article : https://en.m.wikipedia.org/wiki/Mercator_projection
Section : Mathematics of the Mercator projection.
For a map to be conformal should not it be $$k(\phi)=C,h(\phi)=C$$, or the shrinking coefficient shall be not only equal but homogeneous, in order to be conformal ? We then get two partial differential equations and their solution is Simply obtained by integrating a constant towards the variable of integration :
$$x(\lambda,\phi)=Ccos(\phi)\lambda$$
$$y(\lambda,\phi)=C\phi$$
Does this anyhow makes sense ?
