I would like to see integrations added for the mod mentioned in the title.
I confirm it is available for the latest Minecraft version at the time of writing.

What should be integrated exactly

First, make the garlic that minecolonies use for their meals the same as vampirism.
Second, the ability to choose what you want your colony to be, if a vampire colony or a vampire hunter, that would be chosen in a new interface in the town hall block.
Vampire colonies: would have colonists that are not attacked by zombies or skeletons, the colonists would sleep during the day and would work at night, but you would have to feed them blood, whether it be bottles, hearts, etc. The cookery would be able to create different dishes such as blood and heart soup or cooked blood that would better satisfy the colonists. There would be a special type of vampire soldier that the player could give things to evolve, which would be a vampire baron but on the player's side.

Hunter colonies: the colonists of these colonists would be immune to being bitten by vampires, and just like the villagers of a hunter village, they would have garlic blood, so if a player tried to bite a hunter colonist, he would be poisoned. Garlic dishes and garlic bread would satisfy the colonists better. There would be a new job, the vampire hunter trainer, who would act as a soldier, since he would use hunter weapons and would especially look for vampires in your colony. In addition, he could make periodic trips, he would train hunters in the distance and would return with payments for the player. The trip would be theoretical, just like the trips made by the nether miner, he would simply disappear and, depending on luck, he would train more or less people.

Only the vampire baron soldier and the hunter trainer could use weapons from their respective factions.
Vampire colonists would have all the weaknesses of a respective vampire, such as garlic or the sun.

Faction raids: upon reaching a certain advancement your colony could be raided by vampires or vampire hunters, thematic raids of a faction (unlike normal minecolony raiders) would try to wipe out 100% of your population, in addition, hunter raids would make a mini camp (similar to pirate raids) and would have a spawner, now being the hunters' sleeping bags, which would not end the raid until it broke. Vampire raids would create a mini vampire forest with a center that would spawn vampires, which would have to be purified with holy water to break. Hambos could spawn vampires and advanced and normal hunters. In the most dangerous vampire raider raids, a baron could appear as a boss that must be defeated to purify the mini vampire forest. In the same way it could be for hunter raids now with the trainer as boss and he using all the hunters' weapons against the player and his colony.

I can help with

just with testing things and probably explaining a little info about how work minecolonies, in player vision not code one.
