The relevant text:
Aspect of the Wolf: "When you cast this spell you assume the physical appearance and many of the qualities of a wolf(MM 283). While under the effects of this spell, your creature type changes to animal, and your size changes to medium... [etc]"
Awaken: "You awaken a tree or animal to humanlike sentience. To succeed, you must make a Will save (DC 10 + the animal’s current HD, or the HD the tree will have once awakened).
The awakened animal or tree is friendly toward you. You have no special empathy or connection with a creature you awaken, although it serves you in specific tasks or endeavors if you communicate your desires to it.
An awakened tree has characteristics as if it were an animated object, except that it gains the plant type and its Intelligence, Wisdom, and Charisma scores are each 3d6. An awakened plant gains the ability to move its limbs, roots, vines, creepers, and so forth, and it has senses similar to a human’s.
An awakened animal gets 3d6 Intelligence, +1d3 Charisma, and +2 HD. Its type becomes magical beast (augmented animal). An awakened animal can’t serve as an animal companion, familiar, or special mount.
An awakened tree or animal can speak one language that you know, plus one additional language that you know per point of Intelligence bonus (if any). "
So you cast Aspect of the Wolf, your type changes to Animal. You cast Awaken on yourself (you have Natural Spell, right?), and gain 3d6 int, 1d3 charisma, and 2 animal HD. Your type changes to magical beast, but that's irrelevant. When the spell effect ends, you return to your normal type, and repeat, every single time, gaining the bonuses again.
By RAW, does this work?
EDIT: Then you get level drained until you lose all Animal HD (They were gained last, so they are drained first), wait 24 hours and the loss is permanent. So you don't get stuck with useless Animal HD.
