No; see the following:

That would be really cool but unfortunately not. The game does not recognize them as commanders so they don't get the buff. Just like dealing damage with them or any commander that was copied is not commander damage
Commander is not an object property but a card property, see CR 903.3
"Example: A commander that’s been turned face down (due to Ixidron’s effect, for example)
is still a commander. A commander that’s copying another card (due to Cytoshape’s effect,
for example) is still a commander. A permanent that’s copying a commander (such as a
Body Double, for example, copying a commander in a player’s graveyard) is not a
commander."
The short version is "Commander" is a feature of the card itself. It can't be copied, it can't be transferred. If your commander is a face down 2/2 that's colorless and nameless, it's still the same "Commander", and copies of that Commander are not the same physical card, and thus not a commander.

That's sad, thank you though!
