24mm adapter BB on PF30 and BB30
are these adapter BB's (I don't mean the shim, but the entire oversized bottom bracket that fits shimano cranks on non BSA frames) interchangeable between pf30 and bb30? are the outer diameter of the BB30 and PF30 cups the same?

No, 42mm and 46mm respectively - see here for example: Park Tool Co. » ParkTool Blog » Bottom Bracket Standards
