I feel the schedule is fine as is.

Fusion reactor and (when it airs) Interzone replays on Wednesday.

Adding Tom's show to RFW would defeat the object of RFW which is one of the most successful additions in years. We get to hear a much wider spectrum of The Moon's playlist and adding The Gags to the schedule on that day would be detremental to that ideal.

That's my 0.02p's worth.
