It isn't obvious that there is any correlation between pain and GWP.
The correlation between GWP and the value most people place on avoiding
death is probably much closer to zero than to one. I assume it's possible
to estimate this by comparing the present value of a person's income to
the value of life implied by how much that person will pay for safety. I
suspect such comparisons will indicate that GWP underestimates the value
of life by one or two orders of magnitude.
I suspect the freedom effect is roughly the same magnitude as the other
effects.

That would certainly improve the incentives and remove the random biases,
and would substantially reduce my objections.

I'd rather use something like a science court approach - have economists
compete to see whether they can produce an indicator that reliably predict
what a randonly chosen group of people would decide if paid to study the
question carefully.
For areas where such predictions have been proven reliable, I expect voter
pressure would be sufficient to produce the right result without a
constitutional rule. For the forseeable future, I expect there will remain
subject areas for which the indicators have not been shown to make reliable
predictions.
