I like the idea of the InquisitiveInquisitive rogue archetype combined with the City Watch feature for a Commander Vimes-type character concept. Maybe not Vimes exactly, but, y'know, in that line.
But although so much of Inquisitive fits, the whole "sneak attack" thing doesn't so much. Are there any published options for a "swap in" alternative that has a little... less sneak?
Something thematically linked to street fighting or urban brawling would be fine, but the whole sniper/backstab angle doesn't really fit in my mind. That's a problem, as this is the key mechanical combat feature of the class, and I don't want to come up with self-justifications for "re-coloring" the feature every round in combat.
I'm pretty sure there's nothing in Xanathar's or any of the other hardcovers, but is there Unearthed Arcana I've overlooked? What about DM's Guild material that one might be able to convince a lenient Adventurer's League DM is a reasonable substitute?
