Chin's intentions are good, but misguided. I think it will be more difficult to obtain a temporary restraining order this time.  The new EO provides details on how the countries were selected for added travel security measures during the Obama Administration. It includes reasoning given by an Obama Administration document for each individual country. The temporary restraining order was granted last time when both sides said they didn't have time to prepare detailed arguments. The new document provides for exceptions, for example, hardship to a foreign national  who wants to visit a close family member lawfully residing in the U.S.
The travel ban is for 90 days until the Visa program is updated for security. The EO provides the details. There may or may not be more opposition to the updated Visa program.
