SBP to BBP brake clarification

I have been reading all over this question thats been asked a lot about small to big bolt pattern swaps.
What I am trying to find out is;

Can I buy a new big bolt pattern disk and swap it with the small bolt patern disk? Does everything else swap over?

71 Valiant /6 Factory manual front disks.

Edit: Yep, caught my spelling error as soon as it posted, cant figure out how to change it.
