I love this idea. Here's some more:

You could adjust your brake so it's rubbing a little. I've done a few too many newbie miles with a rubbing brake. It definitely slows you down.

Wear a large windbreaker and let her draft.

Carry her gear. My bf makes me do this when we ride to the beach, and then drops me. He's a real prince.

Put heavy tires on your bike, and make sure hers are pumped to the max.

Actually, are you sure her bike doesn't have an issue? Maybe it's not her. Sometimes, it's the bike.
