surgical removal of the lower ribs has always only been performed by the most extreme and dedicated corset wearers- the kind who shoots for a waist you can wrap your thumb and forefinger around- it's by no means necessary and is one of the most risky and foolish cosmetic surgeries you can do

without the image link working it's hard to really say (try uploading it to an imagesharing website like imgur or tinypic and providing a link).

I will say that the majority of pressure of a corset is on the sides and the front bones tends not to be strong enough/ curved enough to apply a lot of inward pressure on the front of the ribcage (too much pressure on the sternum can be very dangerous). While you might see some benefit overtime it'd be a very slow process I should imagine.

Corsets do do a very good job (over the course of months, which is short in corsetry terms) of bending the lower ribs inward, which can help to mitigate the issue of a ribcage that sticks out but for any pressure to the front I'd have a long and hard chat with a professional custom corsetiere and they should be able to come up with a design that suits your purposes as well as explain the risks.

If you upload an image properly I could give you a little more useful advice and comment on what might work for you.
