Reading this question, I was wondering if, at some point early in aviation history there may have been airplane designs or concepts replacing or anticipating variable swept wing by "expendable wingspan wing"?

For example, some heavily loaded bomber airplane barely able to take off with its full wingspan, could jettison part of its wingspan once its mission is completed (having dropped bombs & burnt most of its fuel), in order to flee more quickly from enemy skies.
