Short answer: no. I think the foci of GD vary and, therefore, intensity cannot be quantified in terms of multiple procedures drive. One can be intensely driven to transition, but not FFS. Or perhaps FFS but not, say, a hair transplant. And so on. One may be driven intensely by many things or one, but does that make the intensity additive? Or is it like gravity ... jump off a 100 meter cliff and you will fall at the same rate whether you weigh 60 kg or 90 kg (ignoring air resistance effects) - and will be equally dead when you hit the rocks.
It seems kind of pointless to measure GD intensity if it is sufficient to make you jump off the cliff.
