So... to update everyone, I just finish installing the plates and I think they look great, much better than I was expecting.
The number plate holders were super simple to take off, I'm the worst with DIY as well, so this is like a 1/10 hard.
I used some post it notes to mark where the plate should go after the mounts come off.
The plates were super sticky, but followed the instructions to put them on with soap and they held great whilst installing, I was slightly worried about the screw holes making the finished result look "lumpy and bumpy" but no issues at all.
Here's a picture of the final result (I masked the last part of the plate but gives you an idea)
