Applying for EB2-NIW with a Search Fund business plan

Has anyone ever used a search fund business plan as an endeavor in the EB2-NIW process? Of all the attorneys I have talked to so far, none are familiar with the model but believe it might be a solid case.

I'd be happy to know more details if someone ever did that.

I don't see any issue, but who knows what the USCIS thinks?
