I think that drilling will save you a lot of time. On a ceramic tile I reckon you could go through it as quick as the first cut of the grinder. There is nothing wrong with doing it your way, its just that if there are quicker and easier ways of doing it, why not do it that way? Get your self a set of the 365s and let us know how you get on with them. I think you will be impressed
