As to more massive footprints, I am a member of the Order of Cosmic
Engineers, and I like Kardashev's speculations about Type III civilisations
like the next guy, but the truth is that even a ton of mass is, well, heavy,
and I would not take for granted that most clades quickly end up sculpting
for fun the shape of neighbouring galaxies in the shape of their females...

What if their females are spiral?
