Not really. Atoms are working due to the balance of weak (radioactive decay) and strong interactions (why the are actually able to exist). Especially the former is only applied to extremely small distances, but the second is also appearing on fm distances.

No amount of scaling up would replicate weak and strong interactions that are affecting atoms. Thus, we can't be atoms just as there can't be life inside an atom. Purely because with smaller scale changes the balance of forces and the things get extremely volatile.
