Can you use the actual sink to route an undermount sink hole in a butcher block counter?

I plan to install an undermount sink in a new butch block counter top that is 1 1/8” thick. In order to cut the sink hole, could I simply attach the undermount sink to the counter in the correct position, then use a router with a bottom bearing flush trim bit (1 1/4” carbide) to cut the sink, with the bearing running along the inside of the attached sink? I have read about the method of creating a template out of plywood, but this method seems like it would be easier and more accurate.

Maybe you could cut the hole out roughly with a jig saw and then trim with your flush trim, but I wouldn’t want to do the actual cut with the bit. That would be rough. Plus, you would have to have to have the router set just right to avoid either ruining the sink or the bit and possibly both.
