Nope. Don't upload it... even if it's converting it to a new format, you still have to take into consideration the amount of time and work put into the original by the creator. If they won't grant you permission, then it's probably for the best to let it be... or if you're really desperate, try your hand at making the same thing from scratch. (It's not for everyone, though... but for those who have at least tried their hand at attempting something different and seemingly difficult, it's a valuable learning experience, not just in the "how-to" part, but the "now I know how (name of creator) feels" mindset inadvertently comes with it.) :-)
