To attempt to use more than one Living Language program at once?

What I mean to say is that I've purchased the complete editions for Italian, French, and German, and I'm wondering if anyone else has had the nerve (for lack of better words) to try tackling multiple languages at once though Living Language software.

I started learning French when I was in middle school, but lost that beginner's level proficiency since no one in middle school actually wanted to know the language, they just wanted an elective written down. I didn't study in high school, but somehow managed to help a few friends with basic grammar and so on, which sparked my interest again, though I didn't act on that urge until earlier this year when I discovered memrise and duolingo.  Italian became an interest when I developed a pen-pal relationship with a kind soul in Napoli, and my interest in German came about when a dear friend in college told me she was incredibly nervous about getting back to that language for school. I promised her that I would help with that anxiety, started to learn basic phrases, and would speak or write to her as much as I could in German; somehow, that actually helped build her confidence and she did an amazing job in class.

Sorry, I got a bit off track. Anyway, I was wondering who else might be tackling multiple languages at once and if they had tips.

I was thinking I would separate them from week to week. ex: week one - Italian lessons, Italian radio for immersion, Italian films -- and then a similar layout for the following languages on following weeks. Another idea might be to schedule chat time with native speakers for these designated time frames.
