Let's say that:
*the Republic of the Rio Grande succeeded in independence, then joined with Texas in annexation to the US, quickly followed by the Mexican-American War
*the US had a completely different ambassador after the Mexican American War, and in the treaty, annexed Rio Grande, Sonora, Chihuahua, and Baja California in addition to OTL.

The question is: how do they divide the states up? I'm assuming two things: Texas and Rio Grande have already settled their border at the Rio Grande, and California makes the same demand for its eastern borders.

Would you give California the entire Baja peninsula? Does Texas still sell off its land for assumption of its debts? And for the remainder of the territory, pretty much New Mexico, Sonora, and Chihuahua, how would you divide it up? Would you give Arizona (if it exists) sea access, or is the Colorado River enough? Would you take the Sonora, Chihiahia, and Gadsden Purchase area as a single state (plus or minus Baja California)?
