Swapping the crank probably won't be an issue. However you might need to check to see if your current DR will handle those bigger tooth cogs on the rear. I haven't had Campy stuff since my '79 Raleigh Competition G.S. which I recently got rid of. So some of the few other dedicated Campy people here will be familiar with what those names are and what might be compatible.
Since it appears you have a BSA threaded BB shell and likely have 130mm dropout spacing on the rear, you likely can put most anything on it you want. Depending of course how much money you wish to drop on it as some things will require more changes.
Weekends are usually slow around here. Most everyone else out riding or doing other stuff which I'll be doing too shortly.
