Possibly, yeah. But I think they'd benefit more from the official updates.
I'm not trying to argue that unofficial patches would be a bad thing. I just don't think a source tree from 2003 is a good place to start. Any binary you build off this codebase will be missing 16 years of microsoft's patches. Until such a project caught up with all the changes made 2003-2019, any binary you build off this is likely to cause more harm than good (eg, you fix one issue, and reintroduce every issue that was fixed after 2003.)
The idea's good. This sourcetree isn't. Let's just say 2003 was not XP's golden age. If this was at least SP3 onwards, but preferably 2014+, sure. But it's not, it's SP1.
