Questioner (paraphrased)
1. On a scale of 1 to 10, how similar are the processes of Command-Breaking a Lifeless and Unmaking?
2. Is there more going on behind the scenes when an Allomancer burns pewter? I suspect that the process triggers a "mind over matter" state, where the user's desires are made manifest, albeit in a limited way. If so, can a pewter burner alter their Physical appearance, similar to a Returned (provided they knew they could and had access to enough pewter)?

2a. That is a valid theory. On the right track.
