Is this too much weight?

Hey guys! I am 21, 5 ft, 9in, and somewhere around 118 (I am flucuating so  dont know for sure). To get a healthy BMI I need 125, but I really want to go over that because I feel like 7 lbs isnt enough. I have been around 121 before so I dont think 4 lbs will be anymore visually different than that. Anyway...I want to at least get up to 137lbs at least but 147 is my ultimate goal right now. I looked at this other website that shows you the percentile of your weight and height and 147 lbs puts me in the 50 percentile. I have always been a stick, over the past few years I have have gotten several comments from people that I am and need to gain weight, and I just have always wondered what I would look like un-stick-like. So I figured, hey, why not go to the absolute average weight for my height and age? But do you guys think 147 lbs is too much? Would it be better/ more ideal, or etc to stay a little skinner than that?

not at all 147 is perfect
