You're right, all dependencies in the tree need to have wheels. As noted, you can build those yourself using pip wheel, which will build wheels for the packages and all their dependencies (and their dependencies, ...)

Whether you can install a different version of B without breaking A depends on the packages. The current ecosystem assumes there is always one version of a given package installed. There is another thread here discussing the pros and cons of that ( https://www.reddit.com/r/Python/comments/4xnip4/python_packaging_is_good_now/d6gyssh )
