Interesting situation. I think that in terms of the actual LEED credit requirements, you could do this. It's common to meet SSp1, for example, with a bare-bones erosion control plan (like on a zero-lot-line project).
However, you may have some issues with the Minimum Program Requirements (basic qualification for LEED). Review these, if you haven't, and see what questions come up.
And the discussion forum on that page might be a better place to resume this conversation.
My quick thought is that you might have better luck counting the whole hangar as being within the project scope (and LEED boundary), even if you don't alter it. But that raises issues of its own in terms of the relocatability.
