What if Texas, in exchange for neutrality in the Civil War, had pushed for gaining (or "regaining") territories it had lost as part of the compromise of 1850?
The "Neutral Strip" (OTL Oklahoma Panhandle) and Greer County seem like easy ones to push for. If they really want to get pushy, they could try for all of New Mexico east of the Rio Grande (or lands east of the River south of 32'30, thus giving Texas the Mesilla Valley).
