The only difference between Lui and Alys was the fact that Yamaha was aware and approved Lui but refused Alys. He was more of an official Vocaloid project than she was (Heck, if you ask about Ring and Lui to Yamaha nowadays, they'll flat out say nobody is working on them and such, but don't deny that they weren't to be Vocaloids at one point). I can't even count Lui as "potential" when they flat out implied, if not stated, that he's an upcoming Vocaloid. The only issue at hand was that they never got to release Ring, therefore, not releasing Lui since he was to come after her.

If there were to be guidelines, I think Yamaha's approval is one of the main bulletpoints that needs to be checking off. Other questions to ask would probably be: "Does it have a name/gender?", "Does it have a trustworthy company backing it?" (like for the people who claim to be independant developers but need a company to take in the project), "Which language does it sing in?", "Did the company say that it's upcoming or just an idea?" etc
