Like the Ozmodius said, "It is possible" but there are differences in the edge put on a Feather and the edge that you put on the SR...
First, you need the right SR, IME the type that normally can attain that sort of wicked shapness and hold onto it normally come from Little Valley NY, there are exceptions of course (ask Gugi) but in general The NY straight razors take and hold a very sharp edge...
Second, You need the right stones/hones/films to go there,
Third, You need the skill to take the edge to that level but not take it over the top and create a fagile edge
When all those things come together yes you can get into the same type of sharpness that a Feather has.. BTW then you have to be able to strop with perfection to keep it there, because you can't coat it with the same stuff Feather and others use on their blades :)
Keep in mind that looking at this by the numbers, edge start to cut hair at about .50 Microns the sharpest edges are at about .38 Microns so that only leaves 12/100ths of a Micron to possibliy mess with :p This is why many of us say that we are chasing that elusive "1% better" when we start chasing the edges..
