Its definitely possible. I do it every time I shave. My first suggestion is to closely identify what you are doing with your DE and duplicate the motions, and angles with your SR. I found that the only way to a BBS shave was really knowing what direction the beard was growing in and how I needed to manage cutting it in order to get it completely smooth. I would also suggest that you focus in on how you might get a BBS shave in one particular area of your shave. When you nail it, because of getting the right angle or blade technique, you move on to another area. Every time you nail one area down, you're piecing together the elements of your shave. Don't try to figure the whole shave out at once. Break it down into smaller tasks that can be accomplished one at a time. Maybe the area under your chin is a problem. So you think about what direction the hair grows, how you manage to get it clean with a DE, and you attempt to mimic that with a SR. Think carefully about how you might need to hold the razor in order to mimic what you were doing with a DE.
