The problem is not a big lower body, it's moreso lack of size all over and fat distribution.
Fat is just fat. Don't mean to sound harsh, but work with what you've got (when you cut in the future, even if you do have a big lower body muscle-wise, which will be much smaller than when bulked, is a blessing/advantage)
Quite trying to do two things at once - you cannot be losing fat around the lower boy, while expecting the upper body to grow. Once again, not to be harsh, but you seriously need to add pounds to that bar.
Muscle growth requires over-eating, fat loss requires under-eating.
At best, all you're doing here is making the upper body grow at a snails pace (in essence, your body is simply redistributing muscle proteins), while losing a tiny amount of fat. That method will get you no-where at this stage.
You are skinny. Bring your bodyweight up (EAT), while giving good attention to all bodyparts (so yeah, that includes not just doing basic lifts where lower body gets more attention that upper).
Make your whole body BIG (just as much focus all over), then when you lean out, you may find that you're not as "imbalanced" as you thought you were.
