It could be that maybe some HIIT could at least temporarily alleviate soreness. It's been my experience (not from a competitive standpoint, mind you, but from practical everyday life) that a body in motion tends to stay in motion. Meaning that if I keep moving, I experience diminished DOMS.
I just remembered though that you said you are also doing some SS cardio. I guess that makes my argument look foolish. I encourage you to experiment. I am concerned about overload/over training. Experiment though. Listen to your body. If it starts to shut down, either add some cals (probably not a good idea at this stage in contest prep) or change up the HIIT schedule.
