In case anyone is interested, I ended up doing a route that was very similar to the one I originally posted and I was very happy with it.

As expected, the first 1/3rd was great. As far as the New Mexico vs. Colorado debate goes, I ended up going through New Mexico and was happy with that decision. I've never ridden in southern Colorado, so I can't say that the New Mexico portion was better. However, I do know that the scenery in New Mexico was great and Day 10 from Chama, NM to Eagle Nest, NM was one of my favorite days of the entire ride.

The route through Texas was good with almost 100% of it having a shoulder. From Oklahoma to the Atlantic Ocean is where the routing gets tricky. It's difficult to find shoulders out there and it seemed like half of the shoulders that did exist were rendered useless by rumble strips. This is where you have to strike a balance between riding a straight line from town to town vs. adding mileage and riding on lower-traffic roads. I did a decent job at it. There were only two days where I was unhappy with the route and wished I had avoided the highway a little more.

Now that it's all said and done, I am very happy with the route and would recommend it to anybody who is looking for an alternative to Adventure Cycling's routes.
