Alright so heres my deal,

my lower body is disproportionaly large compared to my upper body. I look really stupid when I am just wearing a t-shirt and jeans as my ass and thighs are big, but my arms and shoulders are smaller. This is also due to genetics as my bone structure is composed of narrow shoulders and wide hips, and theirs really nothing someone can do about their bone structure. Ever since I was a kid really I have been heavy in the legs, played lots of soccer, biking, hiking ect. However I want to mitigate my issue by trying a new format of working out.

Currently I am working out on a 4 a day workout plan, with a 5*5 format.
Day 1 - chest/bis
Day 2 - legs
Day 3 - shoulders/tris
Day 4 - back

Now what I am thinking is putting my leg day at the end of the week keeping the squats, a single hamstring exercise, and a single calve exercise but adding 2 exercises for shoulders/bis/tris/traps/lats. all in a super set form. I would leave chest out as I feel that is the only muscle group in my upper body that is proportionate to my legs. The exercises for these muscles would be different from the ones I have already performed during the week. So for example I would do 3*8 weigted pullup, then 3*8 barbell row without rest and do 3 sets of that then move to the next muscle group. So the new layout would look like this;

Day 1 - chest/bis
Day 2 - back
Day 3 - shoulders/tris
Day 4 - legs/upper body

The plan would be to do this for about 12 weeks to correct some disporportinality I currently have. I would really like to know what you guys think about this plan.

A couple of things to add-
1) I know this is my first post and you instantly think I am retarded when you read this, I would too.
2) My diet is in check. I know the very first thing people are going to jump on is diet, which is very understandable. However my diet is in fact good to go.
3) I Know this sounds borderline like spot reducing which I know is completely impossible but its actually the opposite, more like spot increasing. Which I believe is possible to a point, look at a speed skaters thighs, they are frigging massive.

So please let me know what you all think about this idea. If your just gonna write "thats stupid" trust me I already know this sounds stupid so you don't need to reply. At the end of the day I am going to go ahead with this and act as a guinea pig so I will let everyone know how it worked out. If nothing else it will be a learning experience.
