1)2)3) was replied in comments,
As for hostile actions, there'll be no cross-Atlantic invasion. So normal war cb/raiding is enough hostile.
Actually Mexikha often beaten by GHW by Catholic+Sunni+Shia(sometimes) simultaneously, due to occupy a half Hispania. Really funny lol.
More ideas is always welcome :)

Indeed it seems funny. maybe ivading over ocean is a bit weird but it would be quite funny, never the less i thought about diffrerent conditions of such invasion, max shipbuilding tech or at least very hight tech level would justify such action. Of course i don't know much about coding, i just enjoy other pople's work as a historian and archelogist (and belive me i like your work). About trade maybe there is other way of implementing trade over the ocean, like transattlantic trade post addon conected with shippbuilding tech and trade practices? it would be also funny to conspire against empire with its ovesea enemies :). Sorry for minor and larger syntax errors but console like to corect some words into more native words of mine and it sometimes makes me look a bit dum writer :p

i am playing with your mod over and over and two things bothers me:
1) as i said conquering aztec empire would be lovely (or at least oversea crusade of some kind :P )
2) there is no imperial marrige :( [ i reallly wish that you implement imperial marrige )

1) nah, Aztec overseas invasion is silly enough, and I do not want players are able to do that the other way around. Let's make the world a little more sense.
2) naaah, They're coming for raiding & conquering, not for a peace deal. Would House de Austria(Habsburg) intermarry with Inca, rather than execute them all?
But you may try capture a nahuatl princess and force her anyway, if you want a mixticius heir.

to issue 2: same ting on china its not about sense but projection of power and influence. i think marrige would be good but under some conditions. if a powerfull enemy would attack and marrige ties would give me a mall amout of seafty i would do it. and the other way if you are trying to conquer you dont have to do it only by force but you can simply expand your lineage infuence (like Habsburg did for most of their reign).
to issue 1: what about at least tempering invasion or bringing their colonial empire down (like original event in SSI when you destroy aztec empire and they are retreating)?

maybe ovesea invasion is silly (but inst the whole Sunset invasion silly?), but mariige is much more coplex thing, maybe it schould be aviable only during time when aztec are open, not when they are expansionist, and cost much more grace then chinesse?
one more thing: exept eunhs maybe it would be whise to send royal offering for pagan gods for grace bonus, same way eunuhs work. Eeven more, sometimes aztec emperor could demand certain amout of human sacrafices to be sent oversea from tribatries and vassals...maybe even from those outside their direct influence (for grace or peace)?

i know it is a lot of things but i simply

Is the whole Sunset invasion silly? Yes, We've discussed this with other players before. And I finally agreed that Jade Serpent should be "limited silliness."
So yeah, instead of oversea invasion, a war/cb/event to drive out the Nahuatl invaders from their beachhead in Western Sahara is planned, under developing.
And this will end whole offmap things, once and for all.
About pagan and human sacrifices, I feel vanilla content is doing its job well. Of course I'll look what could I do for better integrating with Grace ( Btw it's called Antilytron in this mod.)

As for marriage for power, the "Habsburg" style is quite unique. Basically there's no other house could achieve their hight. And more, the government of Nahuatl is quite different from Medieval feudal system, it's a theocracy military aristocracy. King, priesthood and warrior compose the domination caste. For the purpose of political or military alliances, marriages among Nahuatl nobles were arranged. But not for foreigners or those who doomed.
If a character becomes the governor of New Mexikha, he'll receive an imperial marriage for sure since he's now a noble of warrior caste.

driving back is very good concept, i am fully satified by no oversea invasion, not because argument ( with is logical and i agree with your point) but rather complications during map converion to EUIV (that would be awfull). yet those marigges and human sacrafice tribute still fits well in my head :)

is this mod still developed?

Not actively, it has already worked as a competent replacement of poor Sunset Invasion DLC and the rest are flavor stuffs.
And CK3 is released so I'll stay maintaining this mod, instead of adding more things.
