You should - it's the simpler solution. Anything else is a waste of resources. I've thought about replacing the first few bytes of memory, thought about ROM overlay with alternative vectors, then thought about RAM overlay, and *click*, there was the idea to just alter these last magic few bytes of Kickstart ROM. So hey, all the resources to implement this feature on a non-VBR-processor are already there if you have implemented Maprom.
Oh, and it's common knowledge
since a few years.
