There have been several Priests in the Archdiocese of Detroit that have asked to say the TLM, I’ve spoken with several about this. Assumption Grotto had hundreds or maybe thousands of signatures collected and sent to the Cardinal a few years back, and nobody seems to know what happened to them, best guess is no response. Many proponents of the TLM are taking a wait and see approach, there have been rumors that a Parish will be selected to have the Mass that is not conducive to it, many believe that the Cardinal does not want this to succeed.
