I could be wrong, but I don't think there is ever a chance to get merit scholarships for transferring. I think your grades make it possible, but think long and hard about it. If you like your school and your school has recruiting in areas that you want to work, I would think very carefully before risking such a fantastic GPA just to move up a few spots.
Now, if you have aspirations like Federal Circuit clerkships or SCOTUS clerkships, then T14 is going to be a must, as well as being a bad-ass in general.
Transferring is tough--and I don't mean getting admitted--you risk losing a good GPA. For me, it was worth it coming from a T4 (top 20%) and ending up a T1 (still top 1/3); but if you're Top 5% at a 40's, you can go almost anywhere.
