Kinda odd?

I finally have a question that is topic worthy.
Alright, I have been thinking lately of the dominant seventh II versus the major seventh II or I in consonance to dissonance.
If you are thinking of the concept terms on the TG chart, or relating to the most outgoing step, the dominant seventh is more dissonant. However if you convert the two to TG numerals and use basic addition, the dominant is less outgoing. For example the numbers for a second fifth chord would be 1 2 3. Or six combined. Most major triad!!
Thinking of it this way----
I V III VII
1 2 5 6
I II VI +IV
1 2 3 7
Lower addition equals more consonance... possibly.
Most outgoing in each---
Major seventh- VII
Dominant seventh- +IV
