It'd be easier just to have AI place Aldric in an appropriate place.
 * If the target is facing/moving away from nearby enemies: place Aldric behind them.
 * If the target is facing/moving toward nearby enemies: place Aldric in front of them.

Making Aldric larger is probably possible, but I'm not sure it's thematic - although Olaf gets bigger during his ultimate. Unit-walking also isn't necessary. Just give him a fairly large hit box (like Thresh and Alistar) and make it so that during Protect he has a very visible particle effect (like Alistar's Unbreakable Will).
