It can transform, but depending on the specific cards involved you might not get the result you're going for.
As you said in your question, only double-faced cards can transform and a copy effect will overwrite whatever face is currently showing. This means if you turn Nicol Bolas, the Ravager Flip into a copy of Thing in the Ice Flip and transform it, the card itself will turn over to the Nicol Bolas, the Arisen side but will still be a Thing in the Ice Flip. If you remove Metamorphic Alteration then you have a problem: a planeswalker with no loyalty counters (because it didn't re-enter the battlefield), which will be put directly into the graveyard.
However, if you turn Bolas into a copy of Liliana, Heretical Healer Flip instead and trigger the ability, you follow the "exile and return transformed" instructions and get a planeswalker Bolas with the proper starting loyalty.
