Alas, it would appear the whole idea was a washout.  
Preliminary investigation ([What is faster: sparse vector or a dictionary? - #12 by PetrKryslUCSD](https://discourse.julialang.org/t/what-is-faster-sparse-vector-or-a-dictionary/112341/12)) seemed to indicate that I could get a speedup by using dictionaries, yet in actual application they are much slower than the original approach.
