One advantage to doing a new section would be the ability to integrate a stepped section that slips into the old tube in some cases. Stronger and easier than doing a separate join ring.
I'm wondering if a new section could be turned as well. Might require some secondary operation on a mandrel if the wall thickness becomes too thin to be managable. Would save the donor 42/53 scope...
