st: deriving a bootstrap estimate of a difference between two weighted regressions

Hi All,
I would like to run two regressions (each using a different weight), and
then get the bootstrapped estimates of the difference. Neither suest or
sureg allows different weights to be used in the two models. I thought that
maybe there is a way of getting the resulting estimate in a somewhat manual
manner, but I don't know how. I am thinking something like this:
regress outcome treatment [aw = att]
scalar ATT = _b[ treatment]
Regress outcome treatment [aw = atc]
scalar ATC = _b[ treatment]
scalar difference= (ATT-ATC)
Then bootstrap the scalar difference to get the mean, CI, etc.
Any help is much appreciated!
Ariel
