Not really sure I understand your question. I'll try to answer, but I'm not a pro.
Whatever the width of your frame's bottom bracket shell, 68mm or 73mm, you must use the corresponding BB width.
Now, the cranks themselves don't care how wide the BB shell is, so you can use the cranks on either.
Lastly, your crankset will need the correct BB spindle length to give the best chainline.
