I am not familiar with such a need so I don't have a strong opinion.

However, if an object needs to be emplaced on top of an existing one, I 
can imagine that the original object was emplaced on some piece of 
memory anyway. In that case, the problem becomes "emplacing an object on 
a piece of memory", which is already supported by std.conv.emplace.

Your idea seems to be for the case where the original object is created 
by some third party code, and that they want us to replace it with 
another object. If they are aware of the wholesale change in the object, 
fine. :)
