Clever, but no.
Our moon didn’t form until long after the solar nebula collapsed.
Observation of other protoplanetary discs and computational modeling suggest the protoplanetary disk collapsed very quickly, in less than 10 million years, possibly as little as 3 million. At the end of this any gas remaining in protoplanetary nebula that were not incorporated into jupiter and Saturn were blown away by T Tauri phase of the sun, and all the major planets currently in our inner solar system inside the orbit of Uranus, including the earth and mars, have accreted vast majority of their masses. The nebula is gone, and only the planets, a collection of planetesimals, and a dense debris disc remains.
It was another 50 million years after that before one of the smaller remaining terrestrial planets collided with the earth in a glancing blow to form the moon.
