There's one potential issue. No matter how technically good you are, if you're tired your execution will be sub-standard. Then, if you continuously train that way you end up ingraining your tired technique. Rest between sets. If she's going to do stuff between sets, pull aparts would be good.
Is her back strong? How able is she to keep bending the bar while lowering and pressing? How well can she stabilise her shoulders (pull her scapulae back and down and push her chest up) and drive them into the bench as she presses? Those two cues IMO make or break a heavy bench press.
I think three days a week would be better. Leave all reps at 5 or less (better for technique practice) and leave the high reps for assistance.
week 1 5x3 at 85%, week 2 5x2 at 90%, week 3 5x1 at 95%. Week four 5x5 at 75%. Week five start again with 5 lbs more. Push the last set each week for extra reps if she wants.
Practice days (two per week)
3x5 at 70%, add 5 lbs on week five. These are her money sets more than the heavy ones, because they let her get tons of practice and build confidence.
Every day do some kind of rowing for higher reps (10-20 per set), some heavy, some less heavy. Aim for 50 pull aparts every training day.
For pressing assistance, only do things that are NOT bench variations (close grip, etc). The logic there is to ensure when she gets on a bench, there is only one lift she is thinking of, and that is bench press. Dumbbell presses, dips, incline presses are great. These should also be for higher reps.
That's basically what I did to take my max bench from 253 lbs to 286 lbs in six or so months (I know, still way low, but a decent improvement in that time frame).
Lastly, if her arms are long a wider grip can help. So can a bigger arch.
