Why not just do S&H as produced 3 days, one day step, one day kickbox and one day yoga or running? I'm not sure if you own any Cathe cardio, but here's an example:
day 1: S&H chest and back
day 2: Imax of choice
day 3: S&H bi and tri
day 4: KPC or CK or KM (choose one each week)
day 5: yoga or 45 min run
day 6: S&H legs and back
day 7: off
I would try this rotation for 3 weeks. I've done it and gotten great results from it.
Hope you enjoy it! have fun!
