Doubtful. First, from the issue I read of Keeper, he never showed the capacity to control magic. In fact, he didn't show much at all.
Second, the Alan is the CHOSEN bearer of the power of the Starheart, it has a measure of sentience.
As Sentinal Alan was the living embodiment of the Starheart.
He only had a body at all because he willed himself to have one.
