How to make a Hybrid workout program??

So I've been doing Turbo Fire for 4 weeks just about and I love it, but I have Turbo Jam and Shaun T Rockin Body workouts. I was thinking about mixing the workouts up that way I'm getting the most out of all 3 of these programs-however I don't want to change the progress I've made so far. I did my first Shaun t workout today (on my rest day) so I haven't actually messed up the Turbo Fire program. I liked it especially since the one I tried was with weights and I currently have no weight training with Chalene. Would it be a good Idea to mix them up? If so, how do I go about it? Years ago I did just turbo jam when it first came out-and I just did 3 cardio days and 3 strength training days (not necessarily any DVD, just basic weight exercises). I'd like to try some more Shaun T workouts but want to keep doing well with Turbo Fire! Really confused!
