The bike will become less twitchy due to a larger trail. You would not want to buy a fork with more offset, since the trail is already on the small side, to start with.
The formula for trail is R/tanH - (offset/sinH), where R is the tire radius and H is the head tube angle. All fork offset reduces trail, so the more offset the smaller the trail and the quicker the steering.
