That would not give him possesion of first base. When he abandons the base he is called out.

Suppose the batter-runner is legging out a double. As he rounds first, he fails
to touch the bag, and continues on to second base. Would you do anything
other than wait for an appeal from the defense ? Running "through" the bag
at first, and failing to make contact would not be any different. If there is no
appeal, there is nothing to call, the batter-runner has acquired first base.
