Yes, it does look like WP_Dependencies would be a good base for dependency management.  That is, however, a large scope and I'd fear a larger scope would be beyond consideration.  

WP_Dependencies helps manage the tree of dependencies; the smaller scoped need would be to collect up a list of latest needed libraries and load the latest one of each or fire an action to notify a plugin that its library load request can't be fulfilled so it can notify the admin user and avoid using the library.
