None of the Jena provided implementations use statement IDs, that includes both
TDB1 and TDB2 which both just store quads directly

Nope. None of the in-memory implementations do this to my knowledge,
because they needn't. I don't know if either TDB1 or -2 do, but I can't think
of a reason they would.
It's possible that someone out there in the community has written one, or
you could try implementing DatasetGraph yourself, perhaps reusing some other
implementation for part of the work.
