I ran into a similar issue a few years back and wrote an updated file block with some enhanced features. It's up on github here: https://github.com/ghostop14/gr-filerepeater. Not sure if it's an exact match for what you're looking to accomplish but you can specify delays between replays and tie it into a mute block to "go silent". There's a couple of example flowgraphs in the examples subdirectory. See if it helps.
