Fairly specific question: I'm a short boxer

[Peter Som]

When you hear "short boxers", you may think: 5'6'' featherweight or lower or even perhaps a couple of weight classes up. However, I'm a 25 year old, 5'3'' and 175 athletic pounds.

Straight to the point. I'm looking to making boxing a serious hobby but would also like to compete in amateur leagues in the future. I have a track background in high school (3 years, 100m dash and triple jump). I was also in ROTC and participated in their after school "special forces" program my freshman year. I've been running to stay in shape sporadically and have just recently begun to learn boxing.

My body is fairly muscular already, it would seem that losing weight for me at this point will be a challenge or near impossible. However, I wouldn't mind fight in this weight class either as I believe I'm capable. So I have a few questions!

1) I've never heard of someone as short as I am ever box at this weight, do I stand a chance?
2) Boxers in my weight class are more than likely going to be taller, how do I train for that?
3) If I were able to lose weight, which weight class should I fight in?

Thank you all for your time and consideration, all the best.
