My feeling is that a bridge should be quite feasible and would offer those
contributors who want it the opportunity to do their GHC development in
git and only use darcs when submitting their final changes or when working
in unbridged repos. I'm not too familiar with the structure of the GHC
repo but I suspect that only a few of the subrepos are big or active
enough that darcs is really painful.
