Depends
It would depend on the radiators that are served by that return line. If you are able to measure the EDR of the radiators that would give us the necessary info. If not then you can post pics of the radiators. Include the height of each radiator.

Even easier
Tell us the size of the boiler (In NET BTU or Sq.Ft. of Steam) and tell us if that pipe's handling all of the condensate or just part of it.

No problem
Roughly speaking, you should have no problem. Try to flush that return out while you've got it cut apart. You won't believe what lives in them.

return under steps
why not leave some means of temporary disconnection for future cleaning, such as a union on both sides of the steps. any part of the piping with a reduction in diameter is bound to collect debris.--nbc

Insulate the copper pipe
If you're running the new copper pipe inside the old iron one, as a precaution, I would wrap the copper pipe in plastic electrical tape to isolate it from the old iron pipe.
