Sounds good to me! I think with supplements and herbs it's worth proposing a study for the Narcolepsy group even if your particular disorder is idiopathic hypersomnia. If the resulting action is an increase in general alertness/arousal than it may indeed be helpful.
I'm incredibly busy at the moment trying to get a cross-disorder diet study ready where members will be able to assess the effectiveness of any kind of diet. The idea came from a couple people in this group that have found a ketogenic diet is extremely helpful. I'll get your skullcap idea posted soon and hopefully it won't take too long to turn it into an actual protocol people can follow.
If you'd like to help setup a protocol let me know.
