Wow, they're everywhere, aren't they?? Are you certain you labled the sole shots correctly? I'd actually want to get xrays, to see what bony changes and rotation(esp left fore) has occurred, before I'd do much more than bevel those massive quarters back to the sole & probably back up the toe of the 'right fore'.
While I agree with Mark that it appears in the pics, due to shadowing, that there may be adequate sole depth, I wouldn't be sure of that, or that the filled in areas around the frog aren't like that because of seriously thin soles more peripherally - it's possible the area around the frogs is the only place with adequate depth, so I would be hesitant to remove any of it without further info, regardless of terrain.
Likewise, while the heels mostly all look a bit high to me, could be because the internal structures have 'sunk' low in the capsule, so I'd be lowering them very gradually, if/as needed. Also frogs all look weak, little used & likely thrushy, so while heel first impacts are important, lowering her heels could cause more discomfort on weak heels & force her more onto her toes anyway. Therefore I'd be inclined to treat for thrush & pad her frogs, to provide extra support & protection, to enable her to use them & develop some strength in them. Given the shape to her rump, while it's hard to tell in the pics, I'd guess there is a fair amount of side to side(higher insides) hoof imbalance in the hinds that directly related to 'upstairs'(whether or not it was upstairs or downstairs that it originated), so may just have to be managed rather than attempting to change it in the hooves.
Agree with BNT that it looks like chronic laminitis may be/have been one of her issues, so I'd also be looking closely into diet & such too.
Do you know the horse's history? Management, lifestyle, environment & diet?
