I perfectly agree that space is being traded for speed. But as per the OP it seems that the storage is much more important than the retrieval, so I think my approach might prove well to be a fit.

As an improved version of storing them as a map, an auto-generator can be applied where based on the index retrieval even contiguous storage can be used without even having to create lookup maps and retrieving from them.
