Again, the whole point of this task/project/thing is to come up with an explicit theory to act as an external standard for ethics. 

And that is the whole point of moral philosophy..... so it's sounding like a moot distinction.

Ethical theories are maps of the evaluative-under-full-information-and-individual+social-rationality territory.

You don't like the word intuition, but the fact remains that while you are building your theory, you will have to check it against humans ability to give answers without knowing how they arrived at them. Otherwise you end up with a clear, consistent theory that nobody finds persuasive.
