I don't understand these steps. Wouldn't the blix just remove what silver image you have? Then you'd just have a clear film and the rest of the steps would be pointless. If the idea is that you can re-halogenate the silver and re-process with a color developing agent, then step 5 should be just bleach, not blix, and I do not understand why re-exposing to light would do anything at all. Re-exposure is a step in reversal processing, but you cannot achieve that here, in part because of the fixer in step3.
