The answer is conditional and "sort of".You mention Keith.He prefered his bullet (358429)which was designed prior to the 357 magnum.This bullet would protrude from the end of the cylinder if crimped in the crimping groove using 357 mag brass.It had to be crimped over the shoulder of the forward driving band which was not to his liking.He therefore chose to utilize 38 special brass for heavy loads.
A load that he liked was the above named bullet,crimped in the crimp groove with 38 special cases backed by 13.5 gr of 2400.Skeeter Skelton popularized a version of this by substituting the Ray Thompson designed 358156 bullet crimped in the bottom crimp groove(that bullet has two crimp grooves.)while using 38 special brass.
What one has to remember is that 357 magnum brass was expensive and harder to come by then.Skelton received bushels of 38 special brass free.It's obvious why he wanted a general purpose load using special brass rather than the magnum.
Today,magnum brass is easy to come by and relatively inexpensive.38 special brass is generally less able to stand full power magnum pressure(even though one may get away with it)due to it's thinner case walls,especially closer to the head.
Also,the above mentioned load is not equal to a full power 357 magnum.The 357 has been watered down over the years but that is another story.All in all,I don't see much logic for attempting to turn the 38 special into a magnum.Some do it for nostalgic reasons I suppose but generally it's wiser just to use the magnum brass when wanting magnum ballistics.
