If you want something more integrated, the receiver will generally need some kind of logic to process a signal. IR will require some sort of view of a flashed signal, it doesn't necessarily need to be line of sight, but reliability will be an issue especially in large spaces. You could use a similar RF chip setup but with the receiver passing the signal to your saber board. In either case the receiver will have to process the inputs, and there would need to be a way to either register the codes or make a learning mode.
If you think about it, it may look better for the blaster block effect in the saber to trigger the blaster. It would be very hard to time your blocking motion to when the person with the blaster pulls the trigger, but the person with the blaster can just point the blaster it will blast in time with the blaster effect. This could also work nicely in that the person with the blaster can fire missed shots without triggering the saber.
