Ok I managed to fix it for myself! Ok it took me a bit of thinking though [I had no idea where to start!], but in the end I just used some intelligence and tried a few tricks and looked at the PHP, tried to understand it and got a grip of it and fixed it for myself! At first I had a problem that it wasn't calling the template for closereason but I also fixed that, but then I had a problem with it showing the reply image instead of close image but I fixed that too!
Thanks for a great hack, now i can superclose threads
