This requires the ability to pause the software, identify all pointers to a chunk of memory and re-write all of these pointers after moving the chunk of memory.

This has been the subject of much research and exploited in languages with managed memory allocation and garbage collection (e.g. Java)

a) There's a performance hit.
b) It only works for such languages. Languages like C/C++ give too much freedom.

To state CoW can be implemented without address translation is a rather extraordinary claim requiring some rather extraordinary evidence besides handwaving.

All in all I get the distinct feeling you're ignoring decades of academic research and actual deployment of alternatives.
