Agree 4 x m5 isn't enough, and I dont think there is room to go up in diameter. The existing bolt holes are a little too close to the side walls to go up in size.
Will try some thin slow setting epoxy on a test piece before I apply to the frame
From the pic. and the few screws that are visible it looks like there might be a bit of room to go larger - but then again it's not a close-up, so do check it. If you're using slow setting epoxy do check the manufacturers curing instructions. Araldite Precision for instance cures with better strength at a slightly elevated temperature - as well a a lot quicker. And remember that once it sets you can't adjust stuff any more - so make sure everything gets properly lined up!
