The concept here is that since the Desert League is a new league that is inspired by a more popular league in another country, some of the logos should have either Mexican or Ullamaliztli/pok-a-tok themes. Kind of like the early MLS with Chivas USA and Real Salt Lake, or the [Tokyo] Giants or
Panamanian Yankees.
So with that in mind here is a pretty simple Fort Worth concept. The W is an upside down M in the style of the 1968 Olympics/1970 World Cup, and the modern national team, and it is in Mexican flag green and white. (I also included a version in tan in case it looks better - and it's hard to see the white on this board)
*edit: obviously I now also find myself halfway through drawing a lizard
