""Indian astronomers analyzed data on the 23 regolith samples studied by the APXS to understand the soil’s mineral composition. These were the first soil composition measurements ever registered from near the moon’s south pole, and the scientists found that all of them included ferroan anorthosite, a type of white rock.
""That finding supports the idea that the moon was once enveloped by magma. “A key prediction of the lunar magma ocean hypothesis is the presence of a largely anorthositic crust,” Vadawale tells Popular Science’s Tom Hawking. This is because during the moon’s magma ocean phase, dense rocks—like magnesium-rich mafic rocks—would have sunk inward, while lighter rocks—like ferroan anorthosite—would have floated to the top."
Moon came into existence as coalesced cloud of matter that remained around Earth after collision with another planet (the rest of it is in our core, most probably causing those huge heterogenous blobs deep inside). At least thats the latest I've heard on that topic.
Maybe its technically possible but I can't imagine small and huge rocks combining together into almost perfect solid sphere without melting it beforehand. If Moon would be shaped like potato then I would more likely believed that.

Anything over a couple hundred kilometers in diameter becomes round given enough time.
An interesting link in the article explains the composition of our (Earth's) Moon:
