Yes, but when you merge the two nets the temporal relationship between the experiences could become garbled. I'm not sure what the result would be, but I'm fairly certain that answering questions such as "What did you do last tuesday?" and "After fixing the ridgeways clenchiration, what did you do?" would be very hard to answer.

Because the really short term memory areas (especially the hippocampus) most likely experience even topology change during the day. It becomes very non-trivial to duplicate and merge them.

I don't know, but I would certainly want to try the experience (as I have described in my own take on it,

Yes, this would be very useful. A source level debugger, or something like the toolkits mentioned in Egan's _Diaspora_ (they even enabled simulation of how the mind would look after accepting certain modifications, making it possible to decide whether they were dangerous or not).

A first step would be something like


  author = 	 {Laakso, Aarre AND Cottrell, Garrison W.},
  title = 	 {How can I know what you think? Assessing representational similarity in neural systems},
  booktitle = 	 {Proceedings of the Twentieth Annual Cognitive Science Conference},
  year =	 1998,
  annote =	 {}

where neural networks can be compared in terms of their internal representations. This approach might be extended to a way of figuring out the structures of these representations, and then visualizing them.

Most likely; we don't have full access to our brain, and a lot of stuff likely resides as wague "sub-concepts", fragments and other neural junk that is hard to relate to anything but affect us.
