There is no official ruling on the card that I can find which would prohibit it. Other official rulings suggest that the card's attack power is zero if it leaves and re-enters play, such as with Book of Moon so if I were asked, I would say that its attack power is zero until those requirements are met. However, an official ruling has yet to be offered as far as I can detect. Therefore you would run the risk of encountering an unfavorable official ruling during tournament play. I also cannot find evidence to suggest that variable attack has been judged to be zero or undefined in the past, so there is no reason for your judge to rule in your favor -except- that the attack power has been qualified as zero if it reenters play.

So, I would say that you could if you were in my house, unless someone brought me an official rule which disagreed, but I would not count on being vindicated in tournament play.
