I've been experimenting with sizes of characters, the are two separate things I would like to scale in addition.

1) Is there a way to scale the walking speed of a single character? (not the distance, but the actual rate they move.) This way a large character or npc will not appear to walk very slowly.
2) Is there a way to scale the hitbox of a single character, or at least not make it scale with size? When you make a character or an npc extremely large, the hitbox can scale to a point nothing can move near or around it, and I'd like to control that, if possible.
