Unfortunately, systematic efforts like this one take up a disproportionate amount of my energy, and are often the first to get dropped when I need to prune my relatively frivolous activities.
If things start to get better in the next few days, I'll jump back in where I left off, or wherever the state of the effort is at that time if it's continued by someone else in the meantime.
Of immediate note regarding your benefit scale, +4 is where I'd generally place not-crap versions of 'once/scene, with a FP' stunts, (in addition to a +2 or reroll, at player discretion at time of use, from the FP itself) if the affected trapping is one likely to see use several times a scene in scenes where the stunt would be used (such as with Fists and Killer Blow).
(for trappings likely only to be used once or twice in a scene where it is used at all, I'd scale back the benefit accordingly, as well as, of course, adjusting as appropriate to how that particular trapping compares to the total uses of the skill as a whole)
