Hiphop abbs and Insanity

I just saw a post about hiphop abbs and I love dancing.
Thing is I just started insanity and I want to keep that up...but I also want to do hiphop abbs cuz thats so much fun looking.
Would it be silly to do done simultaniously

Also whci would be better, as I have a wedding coming up in 2 weeks and need to loose minimum 2 inches of bacfat to fit into my dress
