Thank you Quentin! That was what I intended to do.

I suppose another option would be to move in-order both instructions to the target destination. However, I'm not sure if it would be useful at all because we would have to recompute liveness nevertheless. Also, we would violate the semantic notion of what is a delay slot, i.e. we would end up with 2 or more instructions in the delay slot.
