It certainly can be done, but is probably not necessary.

Freestanding towers are different from guyed towers.

I think you'll find that the tower is limited by the bending stress at the
bottom of
each section.

It is likely that the stress at the bottom of the top section will always
exceed the
stress caused by the mast connection to the tower.
