Well, the Leyes de Reforma were about the mexican government taking power away from the catholic church in every aspect, education, land, infraestructure, etc. In order to try to modernize the country.
Having faith Haciendas produce +2 Culture and +2 Gold instead, does sound like a good idea, though I would also add a gold sum for each religous building a city has, and depending on how much gold gets "taken from the church" you get unhapiness for X turns.
That makes it a tradeoff and a decision you want to prepare for, you get a lot of gold (if you played religous) but it can backfire if you dont prepare for it, kinda like it happened in real life.
Also about coastal forts, despite Mexico having very cool coastal forts, most of them were built back on the colonial period, and after independence Mexico never really became a decent naval power, (which is a shame given its location) if anything Veracruz port has been historically the highway to invading the country. Costal strenght doesnt really fit for Mexico :/
I think something related to post-revolutionary Mexico could fit better, I would suggest:
The Estrada Doctrine
Reduce diplomatic penalties from diferent ideology, as well as unhappiness from civil unrest.
Its passive, but the docrine was all about neutrality, it would allow you to concentrate on boosting your tourism and not loose friends in the process.
Or if you want something pulled right out of the revolution:
"Valid Suffrage, No Re-election!"
-Switch ideology, you get a free Social Policy for each ideological policy you had unlocked, Can only be used once per era.
It seemd OP but cool, something to depict revolution, can use some work.
The motto was originaly used by Porfirio Diaz when he ran against Juarez for the presidency, and ironically used against him again during the Mexican revolution.
