I guess it would be easier to copy/decompress the program to that address. It is not 16k, but ~32k: $8000-$BFFF and $C000-$FFFF (without the area of $FD00-$FF3F).
Autoinit is nothing fancy, you need to add a special mark around the beginning of the ROM (characters: "CBM" and some number, as I remember) and your code will be called from the start address of the ROM. You can do whatever you want to there. Check out how it looks the ROM from $8000. You can even try out your ROM in Yape before burning it into the chips.
