Good idea on the landing foot. That could help angle the hips better. Another cue she could try is to drive the glove side hip to the target.Excellent videos by the way. I'm looking at a little mismatch between her shoulders and her hips. She is very open with her shoulders at release, at the same time her hips are a little closed. Individually neither is necessarily a problem but together they are creating the conditions for the collision down at the release point. Her unusual glove arm action keeps her open, her soft landing pulls her hips a little closed. I would work on the landing. I see you have a couple of videos on your channel for front side leg action, 'step backs', I would try those first. If you wanted to bend the rules a little and try for a quick fix simply have her experiment with closing her landing foot more, this might keep her hips from closing as much.
I'm not sure how I feel about her unusual glove arm action, it keeps her from closing. Normally I see overly active glove arms swimming way out and I'm trying to tone it down. It's possible that it's costing her a little velocity.
