has anyone remastered Knoppix for a blue ray disc?

the reason why I'm wanting to do it is because their is an imaging program called diskdrive xml and they have a modified version of knoppix. however the hard drive image file is about 18gb's and I don't see why I should burn the image files to the Blu-ray then boot off of another disc to image the hard disc.

So I am attempting to remaster knoppix with the hdd image files, then burn that iso image to a blu-ray.

I've looked into mkisofs and genimageiso
everytime I try to make the iso the command fails because of the large image files. Supposedly the iso needs to be UDF but i'm not sure if that will work

any suggestions will be appreciated
