DeathKnights 3.1 min

I'm reaching out for help from the community once again! I've tried three mods that replace undead with death knights, and none of them were quite right.
This one— DeadKnights_c.zip—is very good: the models and icons are great, and the names in the campaign and buildings have been changed. But unfortunately, the balance is completely off.
I'm asking to change the stats and abilities of the black knights, death knights, and knights of darkness in this mod to the stats of Undead → Death Herald/Banshee respectively. And for the neutral—the Death Herald—give it the stats and abilities of a death knight. The ability animations can be taken from this mod (thanks to its creator)— DeathKnights 3.1_min.zip.
And it would be absolutely perfect if the death herald had the same color scheme as in the art. I think I've seen a mod like that somewhere...

Thanks in advance!
