The Daily 5- Is it too late to start this effectivly?

So I have been implementing parts of the Daily 5 in my classroom for a month or so. After reading the book and discovering that this format has students spend like 2 hours in the Daily 5 every day I decided that there was no way I could squeeze that kind of time out of my already cramped day. So I have been having my students spend approximately an hour in my reading block. I guess you could say that my classroom is set up more like a reader's workshop than a Daily 5 classroom as I have taken bits and pieces of information from many different resources to make a unique model that I hope will work in my classroom with the group of students that I have this year. So far we have spent a lot of time talking about the students behaviors should look like and have spent some time creating I-Charts. Unfortunately, I think that their routines and behaviors (good and bad) are pretty set for the year. It is hard to break old habits this late in the year. I think that what I need to do is spend more time at the beginning of the year forming good habits. That is something that I have never really spent enough time on and plan to make a priority next time. You live and learn I guess.
