You’re way overthinking this. Mexican immigration doesn’t even require Mexican citizens to present a passport.
As stated in Timatic, the database used by airlines:
Passport Exemptions:
Nationals of Mexico with a:
- national ID card; or
- certified copy of birth certificate; or
- consular registration; or
- certificate of Mexican nationality; or
- naturalization letter; or
- Matricula Consular; or
- Constancia de Identificacion; or
- voter’s certificate with photo.
("national ID card" here refers to the cédula de identitad personal)
So any of these documents alone will be enough to board a flight to Mexico and to re-enter Mexico. With one of these, she has absolutely no need for a Mexican passport.
She will obviously need a US passport to fly to the US.
No, but it’s probably a good idea.
She is an American citizen with, presumably valid, American passport therefore she can travel on that passport. However, entering Mexico with an American passport generally limits stay to 180 days.
Traveling with the Mexican passport alone will require a US visa.
I recommend traveling with the US passport, but carrying the Mexican passport (or other document such as birth certificate) so that on returning back to Mexico you can show she is also a Mexican citizen and thus not subject to the stay limit for non-citizens.
