THIS. Additionally, I’d do lots of trotting fences (good forward trot) until she is balanced and strong enough to jump out of a good canter. If the canter is unbalanced, the jump will be as well.
Winding down…PM me your email will send dimensions height n photo of oose school…jumps I love Hogs back…can be jumped from either direction no need to reset jumps…and I use one strides to a tight bounce to an Oxer squared low…then keep raising just back rail an pulling out back to widen…it Will get knees n shoulders up…we do a day or 2 in a row then depending on horse let them physically n mentally stew on it for a while…an let them crash …I don t use thick heavy rails that crack shins, falling rails are good scary things…then work on non jumping then revisit it…you would be amazed…98% get it…

Do you mind including me in that PM? I’d love to see what you work with.

I would trot her with poles to small, but ascending oxers, steep Xrails, and jumps with guide poles. Lots of grid work that encourages her to leave the ground from a precise spot and rotate her shoulders up and bring her knees up. Be patient and methodical. Like others have recommended, I would not jump her over solid obstacles until she breaks her bad habits, which may take some time. Better for you both to be safe.
Thanks again for all the replies. I have just been doing hacking and dressage but am going to start adding in the ideas here. 
i did did find some interesting info in the meantime. I found a fb group for people who own horses from the same breeding farm. Seems like the leg hanging is a family trait. Those horses did improve though - they still aren’t super snappy or stylish but they are all described as being scopey and not taking rails despite the form - one of the word of them jumps clean around 4’. So that’s hopeful.
i am more interested in dressage anyway. The jumping is a bonus. If we go prelim one day that’ll be more than enough for me.
i think some people got the wrong idea about her level of training. She has like 2.5 years on her. She just developed some bad conflict behaviour with previous owner so I have been rehabbing her for the past year. I pretty much spent that whole time working on dressage. We school 1st/2nd level now.
Ive just started thinking about jumping again a couple of months ago although I only jump like once a week. My goal until this point had been to make her really calm and huntery - she got anxious about jumping. That is why I’ve been doing really straightforward single fences so he would stay calm. I’ve been working on having her hunter-lope and praising for barely any effort over te jump since she was a bit explosive and quite bracey before and she was so concerned about what I was doing or might be doing that we couldn’t get a distance to anything and she would smash through jumps.
so Im going to proceed with some of the ideas here while keeping things calm and progressing slowly.
Just want to put in a word of encouragement here. After thinking about your post and pondering a bit more, I do know of horses who were “leg hangers” who were successful eventers. One went on to run around Rolex and do fairly well. Another competed at Intermediate and 2* with clean xc and dabbled a bit at advance with less success. The latter horse is very careful,has not had a rotational fall ever, and is honest/rideable as the day is long.
Both horses are quite tall.
So, there are always going to be exceptions to the rule. Not every tight kneed, snappy jumper ends up being good or safe. And not every knee hanger is dangerous. You just have better chances at success with the former than with the latter.
OP, sounds like you have a fabulous training program and kudos to you for taking the time to re-educate your mare.
