It's been done before, Peter. Really though, I was thinking of what the "leftover parts" might be used for if the barrel is indeed replaced. If the bulge is as slight as described, a rebore would take care of it, then a 32 cal cylinder would be found/made and the parts placed on a donor gun such as a K-38. See "Project 616" for a complete description, including discussion re changing from rf to cf.
