It is possible to get into the Lumber Mill early, unlocking the rest of the Lowland Meadows without talking to Ellsworth & Winnick. This results in skipping some of The Weeping Sisters quest line.
The Skip
is performed here,
and this is how it’s done.

I have close to a 50% success rate making that jump. It’s tight, but doable.
Upon getting around the wall shown above, you can drain the Lumber Mill and proceed directly to the Lost Huntress boss arena. This bypasses the dialogue with the hunter’s camp, preventing you from getting the letter for Eleanor, and also does not show the mini cinematic of the Lost Huntress boss silhouette on the way to the arena.
The skip does not break the quest line, as you can still fight the boss, it just removes some of the flavor in favor of speed. You still get to see the cutscene regarding the mysterious messenger who sent the letter to Ellsworth. Ultimately, this might only be interesting to speed runners. I am unsure weather this will merit a fix.
