It is possible that some of the changes conflict with each other so it is possibly not just a matter of applying all of the patches one after another. But I don't know C++ so I can't say for sure. If you do know C++ perhaps you could review the source code diffs and see if they are likely to merge nicely.
I don't know C++ either, but I'd be willing to contribute to a fund to hire someone who knows what they're doing to merge these. Maybe one of the creators of one of these versions? Who's still around?
