I have done many dozens of " morphs" between two isosurfaces, but indeed,
"cross-dissolving" (one image fades out as the other fades in) is a better
term. In most cases, you never actually see two images, just the net
"product" of the two functions, so maybe that will actually get you what you
want.

(untested)
#declare SP = function {f_sphere(x,y,z, 1) } ;
#declare RB = function {f_rounded_box(x,y,z, 0,1,1,1)} ;
#declare MRF = function {(SP(x,y,z)*clock) + (RB(x,y,z) * (1-clock))   } ;

Use that in an isosurface and you will get the idea...
