So I know building muscle now and cutting later would be an initial step away from your goal, but I think it would be a one step back, two steps forward sort of thing. 1300kcal is low, and if you drop that further, there's a good chance you'll be setting yourself up for a nasty rebound afterward. I just don't think you have the muscle base to support the look you want right now. Take several months and do a slow, controlled bulk, aiming for gaining 2-3lbs per month (not including the quick 2-3lbs you'll put on right away, probably in the first week, due to glycogen storage and increased food mass in your GI tract). Understand that you'll put on fat as well as muscle, but that fat will be infinitely easier to strip off later on that the plateau you're at now. And lift heavy with progressive overload on a good, well-designed program...that'll help to ensure that most of it is muscle. It's an initial step away from your goal, but it'll pay off in the long run, since afterward, you'll have a base better suited to support the ultimate look you're aiming for.
