Assuming that the Latin Empire survived, would the population have converted to the Catholic church, or would the country have remained Orthodox? What would also happen to the rulers, would they become Hellenic and/or Orthodox too?
That's kind of what they did though.They could have rebranded themselves as a new dynasty rather than a new state.

As a contrast consider how Mongol and Manchurian invaders ultimately became accepted as 'Legitimate' in the eyes of Chinese. Or even further back, the various dynasties of foreign origin that became Egyptian Pharoahs.

The Taiping rebels were a kind of utopian cult, actually. It's a recurring theme in Chinese history that mass rebellions are centered on religious sects or secret societies (the same was true of the rebellion against the Yuan, which was spearheaded by a Buddhist-Manichean secret society). Generally speaking the Yuan and Qing ruling houses brutalized China during the initial conquests but afterwards were very careful to fit into Chinese state ideology, and ethnic resentment was a subtext in the rebellions that eventually overthrew them but not the primary motivator.Was that sort of thing any worse under the 'foreign' dynasties though? My knowledge of Chinese history is weak, but I didn't think that the Taiping rebellion was based on any kind of 'expel the barbarians' agenda against the ruling dynasty.
I might be completely off base there. I'd still say that foreign conquerors looking to become accepted need to find a way to include existing bureaucrat and clerical classes in the new regime.
That's just simply not true. Medieval Diplomacy was often personal and highly erratic sometimes. Take the first Crusade for Example, where on Paper, it should have failed at every, single, step on the Journey to Jerusalem and the Crusaders managed to do everything they needed to do correctly.
If you put the POD right after the siege of Constantinople and the Latin Leadership manages to ally with the Bulgarians and Serbians they very well could have crushed the Remaining Greek Successor States. And then from that point onwards the situation becomes unpredictable as A Powerful, unified Greece with a Catholic ruling dynasty instead of an Orthodox one is capable of getting actual military aid from states like Aragon, Naples and Hungary.
And pray thell me why Bulgarians and Serbians would have allied Crusaders against their brother of the same fate who are even worse no threat to Serbia or Bulgaria (unlike the Latin Empire).
Because the Bulgarians and Latins did ally if only for a shorter time. https://en.wikipedia.org/wiki/Maria_of_Bulgaria,_Latin_Empress So clearly there was motivation not to simply murder the Latin Empire. The Bulgarians only switched sides when they found more benefit in siding with Nikea. If the Bulgarian-Latin alliance is formed when Kaloyan first offers (During the conquest itself) and holds together things end much differently.
