My response doesn't address Fountas and Pinnell classroom as such, but rather using components of the programs in the Daily 5 structure.  Since Daily 5 does not contain any content, but provides for the classroom structure, any program can be used within the structure. If you look at the goals for each of the Daily 5 areas, you'll be able to see the connections to the goals of F & P. The strategy lessons taught in F & P are most likely built on the same or very similar research based reading strategies as CAFE, so it's a matter of matching them up and using the CAFE menu--and you can add to the menu any strategies you don't feel are covered with CAFE.  The importance of keeping your lessons to the length appropriate for the age students you teach will probably take some work on your part, but if you have others in your building who use Daily 5/CAFE, this would be a great PD or team building opportunity.
