Having played a couple of levels into Halfling Opportunist in PFS, in my experience GMs tend to two types.
Most of the time the GM response has been, "Wow, that's really cool! I'm surprised its allowed, because usually GM fiat stuff just gets banned." Then they happily go along with it and have fun with a unique situation. The trick (besides just getting lucky with a friendly GM) is likely that I try to start out before the game with an ability explanation, the above-mentioned "I promise I'm not a power gamer, I just like the flavor," cringe, and then explain that I'll likely just throw down a roll in combat and not mention it unless I manage a roll above 20 (due to the above mentioned difficulty of actually pulling off CM rolls with a halfling rogue). Then I only really have to try and explain how I'm attempting my exploit if the die lands 15-20 range (and if I get the feeling the enemy will have crazy CMD I generally only bring it up if I roll a 19-20). Once the exploit explanation is approved, I generally do the same thing over and over again, so if it goes off more than once the GM generally just allows it and there is no need for more game-dragging explanation.
On the other hand, the other GM response (luckily fairly rare) is anger and annoyance that I would dare to try such an unusual ability at his table, despite my opening remarks that I totally understand and won't be offended if he decides that I have to use Strength for all my CM rolls and thus I won't ever use the ability since it will basically be useless.
Personally, I'd be fine if I got a friendly "eh...I don't know...that sounds confusing; mind if I just don't allow any GM discretion rabbit-holes?" but unfortunately that hasn't happened yet.
