Can Small Bolt spindles run Big Bolt rotors?

Hello, I have a 75 Duster with Big bolt pattern front drums that Im trying to convert to discs.
This is proof that these cars are subjected to some strange parts swapping.
When I converted my '70 Charger to front discs, I saved the 10" drum assemblies and used them on a stunt car that I had. I wanted the big bolt pattern for it to have a wider selection of wheels.
