There is actually a project to do something similar using conventional breeding. E. woodsii hybridizes with E. natalensis. If you back-cross hybrid offspring with E. woodsii again and again, with each generation you will have plants that are genetically closer and closer to the E. woodsii parent while still having female plants.
