1962 C10 frame swap?

I have a 1962 C10 stepside.
I also have a 1964 frame complete with front and rear suspension.

My current plan is to move the '64 12 bolt rear end into the 1962 truck.
I also plan to swap out the front suspension with whats on the '64. Lots of great articles on this site on that.

other plans are power steering conversion. I have also seen a few good post on this site for this. Seems like a bit more difficult for the '62 vs the 63-66.

bases on this...should I move my cab/bed to the '64 frame and deal with a few mounting adjustments or deal with the mods of swapping the front/rear suspension?
