Incline DB Bench As Main Chest Press?

What are your thoughts on doing Incline DB bench exclusively for chest? Will this create a strange look? Obviously, I’ll include Db pullovers and pec deck, but most of my chest volume will come from doing DB Incline bench. My goal is to get 100 pounds for 12 reps on the DB Incline.
I don’t want my upper chest to look disproportionate to the middle and lower chest, so will incline work the middle and lower as well, or do I have to do direct work for that?
Also, do you guys have any tips on how to get a better mind muscle connection with the upper chest?

Why would it?
