OK, it's been a couple of days with no additional questions added to the list. I'd like to open the discussion on the first 2 questions.

<< Justification >>
1) Why would these hands be playable?
2) What value do they add to/remove from a range?

1) These hands are playable because they can make nut straights. When both pocket cards are used to make a straight, it is capable of building and taking down a big pot.

2) They add the value of deception into a range. These pockets are rated as 0 EV +/- 0.15 bb (most of them slightly negative). This plays into the shania theory. (I can't help but think of it as the 'shunya theory'. Shunya is Sanskrit for zero/void/emptiness/nothing.) The idea here is that pockets that add 0EV to your bankroll over many hands neither help you nor hurt you. They DO make your opponents have to think harder about your range and this makes them more likely to mis-read your holdings, which leads to +EV opportunities.

Thoughts?
