It's been a few years since I've worked with this stuff but I'm under the impression that you can do this sort of replay only for a short amount of time. If so, is there a point?
If the receiver expects a key to have been revealed at a particular timestep, it won't accept a replayed message with that key after that, so you can't record and replay indefinitely.
EDIT: Unless you indeed meant to instantly replay - would the receiver accept the highest strength signal, ie. yours?
