It is considered by some that the Causeways from G1 and G2 project from entrance toward the quarter points of the solstice angles, set off to the East/90* at +/_ 14*, each causeway entrance therefore having its own relative vantage point, and actually negating to some extent considered overall relationship between the three pyramids.

It would be consistent to also consider those points as conceptually projecting Westward , but unlikely that other points would also be considered relative to each pyramid, thus your suggested theoretical points of projection to a large extent are in contradiction to the theory involving the actual constructed causeways.


However, given your points of projection of solstice angles are in-line/set back from the Causeway entrances, and taking into account Westward projection also, then perhaps you could consider the set-back points as enabling the setting sun to be incorporate, as the causeway entrances are naturally blocked off from such factors.
