I think this is just as viable and justified and Godowsky's method(he basically made entirely new compositions based on the same material).
I think these are a great idea, and they make me think, that with not too much effort, it is possible to rearrange Chopin Etudes to cover just about ALL of the technical figurations that have come into use since his time.
Haven't heard of the Wuhrer studies before, but they sure look interesting. It might be less original than what Godowsky did in some of his studies when building a whole new work "on top" of Chopin, but it's probably still fun to play and possibly also to listen to.That would be a nice stunt -- but I have some doubts about the "not too much effort" A fun thing to get started with would be a repeated notes study (e.g. in the style of Campanella, Tarantella from Venezia e Napoli, Debussy Pour les notes repetees, ....), starting from op.10/x or op.25/y...
I'd love to see the Op. 25 no. 6.
