Speaking as a person who currently has 8 adult dogs in the house, plus one more on most weekends, I'd probably tell you no, don't do it. 6 is a lot of dogs, no matter the size. That said, all of mine are quite high energy, so that does add in. That said, once I move out with my two, I'll likely never have more than two or three again.
