Sigh* I'm going to tell you now that I hate doing this. I am afraid that won't happen.

What you may not realize is that your evolutions not only have a physical effect but an emotional and psychological one. 
The werewolf path is meant for those that give into their savagery yet still retain their minds by having a wolves mentality: eat, hunt, mate, etc. They become shock troopers with wolf armies at their disposal.

In the necromancer side you gain a much higher intelligence and understand the concept of death so well you can bend the rules. You are a monolith in a sea of endless life and though you may grow your shadow for a time you will always stand alone. You have the ability to lead but only weaker beings with no minds of their own to speak of

To mix the two would put the phycological and emotional differences in direct conflict. At best you would end up as a dead hound a skeletal dog with little mind. [b]You wouldn't be sentient anymore[/b] and therefore wouldn't be any Stronger then a goblin.
