Here in California, a couple of decades ago, I got the paperwork for several cars "walked thru" at the DMV Main Office in Sacramento while I waited. The reason was that the cars were being shipped to Europe, but I got the impression that they would do this for any customer who had a legitimate need and -- and asked nicely.
So... have you tried going to the nearest DMV (or whatever it is called in Texas) and asking for help? To my mind, 99 % of the solution to such problems is in how you ask.
