On the subject of the bridge, I know staytrem does make 9.5" radius replacement Mustang bridges without the individual saddle adjustment. That's what worked best for me is the old-school, non-adjustable Mustang bridge - just don't use a vintage one as the radius won't line up properly. If you are looking to put a Tune-O-Matic in there, you could probably just order the Fender Adjust-O-Matic hardware in there and make some small wood-modifications to get around the bridge issue (maily filling post holes and redrilling).
As for the tuners, Vintage-Style tuning machines use smaller drilled holes to go through the headstock, you WILL have to redrill those holes for a modern set of Gotohs, Schallers, or Grovers to fit there, basically anything with a bolt that goes through the headstock around the tuner shaft, rather than press-fit bushings around the tuner shaft.
