PC: Spanish reconquest of Mexico in the 1820's

There were a few attempts by Spain to reconquer Mexico (or New Spain, as they called it) between 1821 and 1829, most notably the expedition of Isidro Barradas from Cuba in 1829. All of these failed, despite mexican political division after the dissolution of Augustín de Iturbide's empire, and Spain recognized Mexico's independence in 1836.
So, my question is... how could Spain have defeated the mexican rebels in one of these expeditions and reconquered the country?
If they do, then what sort of compromises will the spanish need to make in order to prevent rebellions from springing up again? Were there enough loyalists there to help them? Would the situation develop into something akin to OTL Cuba?
How does this affect relations with the US, especially on the issues of California and Texas? And could spanish Mexico/New Spain retain the central american states?
 
The Mexican Congress offered the Spanish king the Mexican throne to establish a commonwealth type of situation. If he accepted, this could have started a civil war between the royalist and republican factions that could be resolved with intervention from Spanish troops.

As for Texas, Spain would have more power to deal with it, but there'd still be trouble in South America and parts of Mexico. I don't know much about the decline of the Spanish Empire in OTL, but I imagine that the US MIGHT pull off a victory in a Mexican-American War analogue but it could be a multi-front war.
 
I'd doubt the situation of San Jacinto to be easily repeatable under such circumstances, so I would think Texas would fail to break off.

On the other hand, with the Spanish back in charge, the Colonization Act of 1824 that brought many Americans into Texas in the first place might not be there anyway. Which could mean a much reduced number of Americans (some might still move over, but not as high as OTL).

In that case a Comanche Texas ?

Could be, but I wouldn't think so. The Spanish might put more effort to colonize, and the Comanche could still conduct raids (some were for the purpose to sell stolen horses and stuff to the Americans, for example), forcing them to do something about it.
