While recreation of natural hybrids is somewhat of interest (mostly if I don't own the hybrid yet), I don't think I can count crossing linearis and rotundifolia as actually recreating anglica myself per se; that species has been self-supporting and separate from the parents for thousands of years at least. The ancestral hybrid D. x kihlmannii is a different story. Plus, if I even get linearis to adulthood (and they're still less than 1/2" across despite all the time they've had to grow so far), I'd much rather attempt if the opportunity arises crosses with species like filiformis, capensis, if it's possible (and theoretically it should be) things like affinis or madagascariensis, etc.
Also, while some fertile hybrids are interesting, I personally would much rather retain most of mine as sterile; lineage can't be crossed back and confused with anything later on and my crosses like brevifolia x tokaiensis (brevi x spat I can't say for certain is an actual success yet; still very, very young) are more than prolific enough as they are.
