if an creature is immune to a certain damage type, and is later subject to an effect like the blood hunters amplified blood curse of the mark or an hallow spell cast by an cleric, will the new effect "override" the previous immunity, making the target loose its immunity, or will immunity and vulnerability coexist, making the added vunerablillity completely pointles since something * 2 * 0 is still zero? Does an similar property apply to damage resistance and vunerabillity?
Technically speaking vulnerability doesn't even override resistances. RAW they both get factored into the damage calculation - which means odd number damage actually does less to a target with both vulnerability and resistances than it would to a target with neither - since it gets halved and rounded down then doubled. Most people I'm aware of treat having vulnerability and resistance as having neither - probably because they assume it works like advantage and disadvantage - so the odd case above would be hand-waved away.
So as you found out - innate resistances/vulnerabilities/immunities persist regardless. Nothing ever overrides them. Even the Elemental Adept feats say the "spells you cast ignore resistance" rather than saying it removes or overrides them.

Why don't you double the damage first then half it? That way X×2×1/2=X instead of X×1/2×2=X-1.

Yea - I agree. I was surprised when I saw a sage advice or tweet about the order of damage calculations. You'd have thought resistance vs vulnerability would work like advantage vs disadvantage because like those resistances/vulnerabilities can't stack. You either have them or you don't. But I guess two different people wrote those rules? /shrug

i am soup, with too many ideas (all of them very spicy) who has made sufficient homebrew material and character to last an thousand human lifetimes
oh wait XGE totaly answers this question nevermind i guess... (the answer was no, immunity persists)

Well, it's dumb, but its the rules as written I guess...
