You get the same thing done in LR by: - Adjusting the color image the way you like. - Creating a virtual copy. - Doing a B&W conversion on the virtual copy with Silver Efex Pro. What LR is doing with files behind the scenes is inconsequential. The original image file will be untouched, you can return to it any time you want, and it sits in the catalog right alongside the virtual copies. I'm not sure in detail how SEP and LR interact, but if SEP is operating as an external editor, LR will have created file with all your adjustments fully rendered then passed that to SEP for processing. If SEP is operating as a plugin with parametric processing, it will just modify the virtual copy. At any time, you can go back to the original, your color rendered version, or the B&W version, and do whatever you want to do with them. You can make a near infinite number of virtual copies. They live in the catalog database as a few hundred bytes of data to provide the reference to the original file and whatever parametric adjustments you have made. When you export one, you create a new file with all the rendering and metadata just as you created it, independent of LR and the original file that it was derived from. In LR you can stack masters and virtual copies, put the one you are interested in on top, and collapse the stack so you see only the one on top. You can expand the stack and see all the others any time you want too. That's pretty much the same thing as making separate layer sets in a Photoshop image file and only showing one or the other at any given time.
