Going off of Chuck's Ratchet and 1g8, it WILL work but you will have to run a 10t driver and file the teeth on it. The pins will also rub the hubshell, but after it wears a small groove into the hubshell it will work no problems.
415H has slightly wider pins than the 1g8 so it would rub the shell too much to function properly.
I suggest just getting the Keychain, it drops May 27 and Empire is accepting pre-orders NOW.
