I guess there's 3 ways to look at it...
1. No Con = No casting without a sacrifice. Ouch! Harsh.
2. Drains lifeforce = Eats away Charisma instead of Con. This would 'hurt' them quite a lot to use, as IIRC, it powers most undead abilities... Would unfortunately make sorcerors cry.
3. Can use as they like. Frankly, how many PCs are going to make themselves undead just to escape some part of component costs. How many GMs would let them.
I think transforming into one of the undead temporarily would be pretty difficult... IIRC, only Shapechange can do that and has a component cost over 1000Gp by itself...
Personally I'd lean towards 2. - I like the ideas of allowing the Blood Mage to cast if their 'caught short' of blood, but also 'forcing' them into making sacrifices... for PCs it's what they've taken the class for. For BBEGs, it makes them all the nastier - how many players are going to like the guy after finding a few hundred sacrficed villagers corpses!
