could I use fibreglass and filler just to get her through the MOT? car currently not taxed or MOT'd
I did that job, it wasn't that hard. As you can see from the pics it was pretty gruesome, a lot worse than your. Most of the time taken was preparation. I bought repair panels, which fitted ok but were a bit generous in places and not generous enough in others, so I cut bits off them and added them elsewhere.
It's a good opportunity to replace the bulkhead/windscreen seal. Here's a few of the pics - more available if you're interested.
