I personally don't think so. I think weaker aspects create patterns of events, consciousness and behavior that are less recognizable to the person who has them, and to others, but patterns nevertheless. Just because a pattern is less typical or harder to identify doesn't mean it is not important.
Aspects represent patterns.
Families of patterns, really, categories of patterns. Dynamic patterns of interaction between symbolic clusters. Patterns of meaning. They are not forces, whose power to move things can be measured. To think that a square is somehow inherently more powerful than a semisextile is like thinking that a long word is inherently more important or meaningful than a short word.
