I believe this to be the most interesting question... since the user 
does not know his connection will be relayed via a client-exit, there 
will only be encryption up until the last relay (the one advertising 
itself as an exit). Therefore, even if you re-encrypt the data for 
transfer to the client-exit, it will now be *two* hops being able to 
read the user's traffic in cleartext.
I don't think that's an improvement... I'd even go as far as saying it's 
the exact opposite of what we want.

Plus, having the last relay re-encrypt the connection will add 
additional CPU and RAM load, which IMHO is not a good idea.
