As hiring gets tighter, expect to see airlines go back to traditional requirements/preferences...IFR and ME time. Their mins may not change, but competetive times will.
As others have said, towing is not the best time for airlines...it didn't matter when they were desperate to hire 300 hour pilots, but those days are gone for the forseeable future.
Also towing is DANGEROUS...
The FAR's do NOT allow towing...it always requires an exemption. This is so the FAA can keep their responsibility at an arm's length.
IIRC, there are certain parts of the tow regime where an an engine failure might not be recoverable.
