well.... my mate had a koxx kenny thing, and it cracked in 4 places, he drilled each side of the cracks and it never started cracking in the same place, it then cracked on both dropouts and he couldnt drill them out, so it eventually snapped there, so it will work, but you will have some horrible noises and flex coming from your frame, this also had a flat downtube, was the most abused frame i have ever seen, and from a koxx it lasted nearly 3 years, with alot of heavy riders . so it will work, it'll just be gross and will probs crack in a different place in 3-4 months .
