copper chloride bleaches the fully developed silver and then re-halogenates it. Re-halogening is the key, for example potassium ferricyanide bleach does not re-halogenate the silver. Correct me if I am wrong.
While the bleach may convert the silver to silver chloride, modern films are mostly silver bromide with some silver iodide. In addition all the sensitizing dyes are washed out. This thread does not describe something wondrous but rather a pointless experiment. Sorry.
A rock pile ceases to be a rock pile the moment a single man contemplates it, bearing within him the image of a cathedral.
