I don't think that's the issue - it's simply too big, especially at the shoulders. The seams for the sleeves are part way down her arm, not up at the shoulders like the prototype. Removing the liner or filler won't shorten the length from her neckline to the seams for those sleeves, it will just make the jacket fit looser and hand down even more. Maybe switching out the body for one with slightly broader shoulders and a larger bustline?If it's real leather, I wonder if it can be conditioned and broken in? Maybe the liner just needs to be removed or some filler in the jacket taken out? Wont know until someone starts messing with it. Perhaps a custom jacket can be produced as well?
