Ok, RA AU idea:
Modern au where the rangers are basically high level thieves (like million dollar art thieves, not regular old burglurers) and Will is their newest member, at age 18.
While he's on a heist with Halt, they're almost caught by a detective and the group of security guards with her. One of whom is Horace Altman, (who's the same age as Will obviously)
It would be enemies to lovers Oakleaf Knight/Willace, where the two slowly fall for each other over the course of multiple heists.
Also the previously mentioned detective? Pauline Dulacy. So while Will is going through his own little Enemies to lovers plot, so is Halt! (And Crowley too for all you Craltine fans out there)
And then, as the C plot, Alyss, Pauline's detective student, is working with Cassandra, one of the wealthy people who's been stolen from, to try and stop the heists, and is slowly finding that this wealthy Heiress isn't as stuck up as she first thought.
