I only took a very quick look at the diff file. I have a couple of questions:
It looks like that for certain types, (C++ arrays, vector<int>, etc) we want to use binary_save/load to leverage on the fact the fact that we can assume in certain situations that storage is contiguous.
Note that there is an example in the package - demo_fast_archive which does exactly this for C++ arrays. It could easily extended to cover any other desired types. I believe that using this as a basis would achieve all you desire and more which a much smaller investment of effort. Also it would not require changing the serialization library in any way.
If you check the post I made last week I did just this for std::vectors of POD types, this went from 9.5seconds for a 50 000 000 element vector of int to ~ 0.5 seconds. Very worthwhile speedup for a lot of common use cases. Martin
