Yeah DS won't be a problem I think, and as for quadraxis, do we have confirmation that you can actually damage the smaller antennae on the head without it? I know we can destroy the main antennae.
If so, then yeah, that just leaves accessing the caretaker drone. If a way is found to bypass caretaker, get screw early, or to damage the sonic locks without echo visor then yes, we might be able to skip the echo visor.
Which would also have the advantage of letting us skip both the DS2 and possibly caretaker drone fights. A good time saver for sure.
