Idea for new grading system

Disclaimer: This has nothing to do with dynos, but i wanted to submit this idea to the climbing community and this seems to be the only sub that allows you to post without requiring a certain karma :/

I'm a novice climber (started climbing less than a year ago) and since i discovered the grading system i've been thinking that it is too generic! For example i've found myself climbing V5s that mostly require pulling strength while struggling with V3s that relies on finger strength. So i came up with this idea: If we can define which are the fundamental abilities required in climbing we could start grading them separately for each climb. Suppose to consider [Pulling strength, Finger strength, Balance] and assigning to them a value from 1 to 9, then we could describe climbs of the same grade in a more fine-grained way. For example two V5 can be graded as 5-3-4 and 2-6-4 hence representing much better what skills are necessary to climb them. Obviously this is just a simple example, I think we must consider at least 5 different skills in order to describe well every climb.

I want to know the opinions of more expert climbers! Do you think that a grading system like this would be useful?
