I would like to see integrations added for the mod mentioned in the title.
This mod is going to remain in 1.16.5, no plans to add it to any other version.

What should be integrated exactly

The major issue I bumped into has to do with how dragons work; each of the three types has a unique restricted diet. When you become a dragon, this gives you a unique hunger bar themed after the dragon's diet, but this bar completely overwrites the blood bar so while you can play a Hunter fine, you can't be both a vampire and a dragon at the same time (I haven't experimented enough to see if the blood bar is simply hidden or if it's overwritten it entirely.)

(It's also a miniscule and unimportant but I'd also love to see if there were vampire customization options for vamped dragons' default skins)

I can help with:
Additional comments:
This mod is very new and updating at a fairly frequent pace, so nailing the specific version might take a bit, I'm unsure if the coding would allow superceding of the blood gauge over the dragon's unique hunger gauges, but felt it couldn't hurt to ask and see, worst case get it put on the "in the future" list.

hmm sounds interesting id love to see this in practice
