Yes, Zepir's map editor allows up to 480x480 (Well actually it allows up to 512x512, but beyond 480x480 you'll encounter problems). However, the problem that remains is that you unfortunately can't change certain map properties such as the loading screen with a map higher then the Blizzard regulation maximum. If you're fine with that, however, then you can grab the latest version of the editor that's compatible with TFT from the tools forum.
