Yes! I'm very interested in polyphasic sleep and have tried it before. There are many different variations of polyphasic sleep and some of them are easier than others to adapt to. I did experiment with it for fun and even though I went back to "normal" sleep later it was still worth it because I learned so much about sleep, sleep cycles, sleep stages and things like that.
By the way, there are people who question that the standard 8 hour sleep per night is not the natural way of sleeping. For exampel there is a book called "the slumbering masses" that suggest we slept in two periods during the night. You can also google "segmented sleep" or "biphasic sleep"
There is great information on this site
http://www.polyphasicsociety.com/Sleep is a complex thing if you consider all the variables that affect it so I think it takes a lot of knowledge and commitment to change sleeping habit, but I certainly think it's interesting to experiment and see what happens as long as you do it in a safe way for yourself and others.
Regarding meditation and sleep. One benefit of polyhpasic sleep is that it might be easier to practice lucid dreaming, if you are interested in that. I also think it might be easier to develope continous mindfulness with restricted sleep if you are on a retreat for example.
Sleepiness can also be used as an object of meditation. Shinzen Young have a youtube video on this.
