The main issue you'll find with going the C++/RTTI route is that #2 no
longer is possible, since virtual objects are not POD, so you can't
safely write them through a ringbuffer (or copy them around manually in
general).

The intention of the size() member function is to allow you to memcpy()
the object without knowing its type. Is that not enough?
