I do not believe any conversion to a boost::fusion::deque, using the generic boost::fusion::convert functionality, will work. I discovered this bug testing out a PR for the iterator library where a suggested change has been implemented so that the zip_iterator in the iterator library can use fusion sequences, and through the fusion adapter, std::tuple, as the tuple type for the tupleiterator of a zip_iterator.
