I thihnk I like this idea. Aura Siphon does synergize better with teleport, and whenever I'm a tele-stabbing wizard, I don't use Amefyst very often, since I need the mana for teleporting, and when I'm a shooting wizard, the point in Aura Siphon makes it a lot more work to get Magic Crystals.
The downsides I can see are that there would be 3 multilevel skills in the left tree and a telestabber has her combo down at level 2 instead of at level 4. This might be good since it would allow for more flexibility after you have your combo, but it also makes her get her core build really really early.
