I mostly avoid 1500 point games, I find VC are very weak in this point range, we need the lord choice in 2 k games or smaller strong enemy units in 1k.
That being said, 2 lv 2 vapire heros like above is good.
However I would consider giving one a helm of commandment. Then give the Wight King a Sword of Kings and The Acursed Amour. (stick him in a unit of GG with banner of barrows) Now you have a fighter with 3 attacks with ws of the vampire, killing blow on a 5 and a dragon like toughness. This should let you handle most fighter heros now much stronger than in 1k games because they have access to more magic items.
