Presenting a fictitious Disney World passport to law enforcement as a real ID would be just as much as a crime as trying to deposit fake money from a child's playset at the bank. It's the action of trying to deceive that pushes it into criminal territory.
If it has his true name and photo on it, it's real identification. It's just not official or governmental identification. What makes a forged ID "forged" is not that it's not state issued, it's that it passes itself off as being state issued.
A reasonable person would interpret it as a department of defense ID. That's the standard that is going to be used against you in court. Identification intrinsically has provenance at the core of it's concept.
Just like you'd be fucked if you tried to deposit dollars for the federal bank of amerigo, your fake country.
