I just do a JP spring kit and a set screw above the grip screw on my AR's (Loctite blue in final position).
I go a bit further, to take some off the back of the trigger, to adjust more creep out, but this requires a bit off the disconnector face as it only can move within the trigger after adjustment.
Gets me a minimal creep trigger around 3.5-4#.............for $20.
But................the JP springs and set screw may get you what you need without any further mods.
