Drilling out the frame today...Any reason not to? Mafac or Suntour?
I've got the Mafac Racer brakes...I don't like the setup issues. I don't like the flexy nature of the brake. They work okay.
I'm thinking of drilling it out and using a NOS pair of Suntour Cyclone calipers with after market cartridge pads. I know single pivot adjustment might be just as much a PIA...but I've got to do something...
Along with ditching the stock Mafac levers I'll upgrade to Tektro levers. Is there any reason not to drill a frame? It's really not that classic of a frame. Its a middle of the road japanese frame.
Would the Tektro Nutted Dual Pivot long reach be a better upgrade? I think the Cyclone will be pretty nice. They look every bit as good as the Superbe.

Are you talking about drilling out the nut-side hole of brake bridge and fork crown for recessed nuts? I wouldn't have any issues with that, particularly on the frame you describe. If you or someone wants to go back to nutted, it's a simple matter of an insert. More drilling than that, and I'd have to have a clearer picture of what that might be.

you need a reverse drill bit or a short regular bit and 90deg drill to do the brake bridge. you don't want to just drill through both sides. if the hole on the side toward the caliper is too big the brake can move up and down (more likely down) when applied. I would actually look for a donor brake to get a nutted pivot bolt from. you can use most any diacompe brake to do this.
what is your issue with sidepull brakes? once properly adjusted they are no more bother than any other brake type.

OP - make sure to put a little mineral or 3-in-1 oil on the drill bit as you start, and be prepared for a jam if you don't go nice and easy. Pay close attention to the angle of the drill as you go!
Cyclones are sweet, and significantly less of a PITA than the center-pull Racers IMOE.
Good luck!

It's much easier to just drill all the way through, and then use an insert on the back to prevent the pivot from moving around.
