Getting a list of LessWrong approved questions would be awesome.

I'm not sure whether Lesswrong approval is the way to go. In the outside world few people care about Lesswrong.

I think if the project is in a later stage it might make sense to mail a bunch of domain experts and ask them for guidance.

I could also imagine using biology.stackexchange as a platform to discuss which tests should be used for a specific issue.
