Origin: "Nanobots" (name TBD) "Clusterbots"

Description

A Machine playstyle in which pops are rapidly assembled, but are used up to create buildings, ships, and space structures. Colonizing new worlds will be a challenge for the nanomachine empire in the early game as it learns to adapt to the various planet types. Nanites play a role in this empire's functions. Nanotech is highly desired and this empire may quickly become a feast for power-hungry empires. If this empire can discover what lies behind the locked parts of its memory vaults, perhaps its ships can become more than just debris piles waiting to be scooped up.

Possible name: "Clusterbots", "Replicators"

construct entirely new worlds from nanites.
a nanite world doesn't seem too farfetched. There is a mod out there, Planetary Engineers I think it is called, that lets players build a size 1 world in space.
that would be a good way to burn nanites, assuming constructing planets is designed to be expensive.
Or expand existing Machine worlds using nanites using some cost calculations that scale with planet size.
