No, it is not, even if ignoring the fact that the valves are not pin compatible.
I cannot think of any Noval Valve I would suggest instead of the 5687 and even the cheapest 5687 easily trashes all the russian 5687 wannabes (6N6, 6N30 et al).
If you want to improve the Lux, consider using the tube with only one halve as follower and using the second halve to cascode the follower, makes it basically a Allen Wright "Super linear Cathode Follower" with a choke instead of CCS.
Sometimes I'd like to be the water
sometimes shallow, sometimes wild.
Born high in the mountains,
even the seas would be mine.
