Barbie and the Three Musketeers
What they share
Both films are directed by William Lau, and they both carry the cozy, playful mood tags, and they sit in Animation / Family territory. If that's the register that drew you to Barbie as The Princess & the Pauper, the second film will land in a comparable space — through a different lens.

What Barbie and the Three Musketeers is
A fairly straightforward attempt to broaden the Barbie brand. Country girl Corinne journeys to Paris to become a musketeer, only to find three other girls with the same ambition. Together, they use their talents to foil a plot against the prince. Achieves exactly what you'd expect.
