i will say that mostly i will be attempting to run Curseborne with RAW. to lean into the Curseborne approach as much as possible.
reading it over, there really isn't much that i strictly feel i need from VtR that is missing.
sure i may drop some names here or there. Daeva / House Bathory, Ventrue / Heirs, Mekhet / Ascetics. really just missing Gangrel and Nosferatu. Nos may be hard for me to lose, so they may be the one i want to pull in.
from Kindred mechanics, tho, i think we're only really missing Blush of Life (which doesn't seem to be needed in Curseborne), Blood Bond and Predatory Aura.
Blush of Life you can port as is, just change it to bleed a Curse die, or Hold 1, depending how often you want it to come up.
do the same for Kindred Senses, but build it off of the +1e the Hungry get at night.
Blood Bond can actually be incorporated right into the Bond system, so that's easy
The Cleansing is more narrative than anything else.
I also haven't yet seen a Blood Sympathy analog in CB, so that's something to keep an eye out for.
Predatory Aura is a bit more complicated, however. I'll need more time to mull it over and will post separately about it.
