But if the radius is constant, the lattice gets thicker at the top.
I see the problem now: the vertical spacing is constant (0.5) but the
horizontal spacing shrinks (in proportion to the diameter of the cone).

Will elliptical components do?:

#declare h=1;
#declare mh=100;

blob    {
        threshold .5

        #while (h<mh)
        #declare f=(mh-h)/mh;
        #declare a=sin(h)*5*f;
        #declare b=(h)/5;
        #declare c=cos(h)*5*f;
//      sphere{<a,b,c>,f/2,f*20}
        sphere { 0,1.5,1
                scale <f,1,f>
                translate <5*f,b,0>
                rotate y*degrees(h)
                }
        #declare h=h+.5;
        #end

        pigment {color rgb 1}
        }
