Seems as though you should just import your data as two fields, since none of
the 6 components appear to be shared. There's probably not any memory savings
in the 1-field approach, and you wouldn't have to do any of the Replace
tinkering (which can be tricky when working with attributes, as well as with
invalid positions, etc.)
