Did Armsmaster Attempt to Replicate Flechette's Power? Why Couldn't He?

Why didn't he try to replicate flechette's perfect power when he could do so to Clockblocker's in canon that is. Did he just think it wasn't possible. It was well known after the behemoth fight was leaked to the press tho. Knowing Armsmaster he would have tried to replicate Flechette's power. Whether or not it would have taken too long to study and replicate or he was unable to do so is an entirely different matter. But Wildbow brought up the fact that he could replicate 2 separate powers- Miss Militia's and Clockblocker's (he doesn't really put any limit or constraint to that skill) and if my memory serves me correct it's never brought up in the story again. Tinkers casually replicate other powers as well. Such as Leet creating a bug control machine. Tinkers are almost deus ex machinas, their ceiling is just their imagination.
