That's perfectly reasonable.

I would suggest generating just VC2k5 project files, and then
modifying the build scripts to upgrade them first if required. We do
something similar with wxWidgets for pgAdmin's use - albeit converting
VC++6 files to 2k5 - using the /upgrade option in vcbuild.exe. I
assume something similar is feasible for 2k5 -> 2k8.
