Sounds good...
after reading your OSH, and then looking at DNDNext, I have had some ideas swirling about the head......
Which in turn have been swirling back around something else I came up with at some point (I think I came up with it, but I could be mis-remembering) in regards to a Supers idea I had once....
You you basically get Pips in specific skills, but no stats are associated with those skills. In short, a +3 in Perception is simply a +3 in Perception.... Then the GM would pick a stat, and a skill, and you would roll, adding in the bonuses for those 2, and that would be your total -- the stat selected would be based on how the character was attempting to resolve the issue in question... Plus, you could combine multiple skills (and note: I am likely going to use something along these lines for Novus version 2 whenever I decide to do it).
For example, you have a skill -- Locks -- you want to pick a lock, the GM calls for Dex and Locks, you want to figure out a puzzle lock, the GM calls for either Int or Wis and Locks, finding locks? GM calls for Wis, Locks, & Perception
I would also like to perhaps suggest using, for OSH, the 4 Saves you came came up with instead of the one for each stat...
