You don't need to notch the studs. Just replace a section of drywall with
smooth-finish plywood the same thickness, screwed to the studs, seal
appropriately, mud into the drywall, prime, and paint. If you do it
right, it'll vanish completely.

That certainly sounds *easiest*. I'm concerned about thickness: all my
resources talk about using backer boards that are 1" or 2" thick.
Use a board bigger than the back of the sink (ie, bigger than the 2x6 the
book says to use), and lots of screws into the studs. A 12" tall panel of
1/2 " or 5/8" plywood, across 3 studs, with 4 or 5 screws per stud, will be
plenty strong enough to resist the twisting action from the weight of the
sink. If you can exactly spot where the bolts for the hangers need to go
before you put the plywood up, some bigass fender washers on the back,
versus butterfly bolts or whatever, can't hurt.
