with bone wall, you would get the number of counters currently on the existing bone wall. upped will be the same number, it will just overwrite the first one, same as weapons and the other shields. i see where you were going with that question line, but i think it would be OP to allow you to make accumulative counters on the copies.
also, note that untargetable permanents are not targetable to be copied, such as the glories, hopes, etcs. however, permanents that state "cannot be destroyed or stolen" *can* be copied, as they are not being destroyed nor stolen.
