I dont think it is gonna happen. As I understand it the Kayfun is a threaded body like Vivi Novas where the tank itself is the cohesive part of the device. For glass you need a device that is either simply press fit in which there is the chance of coming apart unexpectedly or some other mechanical connection like a threaded center stem, solid center or outer sleeve to hold everything together. I could be wrong but I dont think the Kayfun was designed to be glass friendly. I dont have one so I am just going by what I have seen in pictures so if anyone has information otherwise then please let me know.
