The four points you listed are for Sacraments. Since Mass is a Liturgy, there’s a lot more going there. For one thing, what is the matter of the Mass? The Sacrifice? The Readings? You can probably quantify the legality of it using those four points, but since there is a lot more going on in Liturgy than in conferring Sacraments it will make it rather complicated. Also, what is the valid form of Mass? Remember that in many abuses, many of the words to be used in Mass are altered, but it does not invalidate the Mass.
I’m not saying that you’re entirely wrong, but from my point of view I think a different approach to determining validity of the Mass should be taken just because a Liturgy is far more complex.
