Breaking into Corporate banking from Commercial Banking

I just recently started at a middle market commercial bank in the midwest. My first position is a ~9 month rotation where i'll spend weeks learning the different areas of the bank with their teams. The longest rotation is credit (6 weeks), and a 10 week rotation in the group you work best with (it will be credit again).

After that, I'll start as a Credit Analyst 1. We do a formal credit training program during either the end of my rotational when i'm working in credit, or right when I start my Credit Analyst position.

The bank serves the middle market business and is small, with just less than 1b assets. We are growing fast, so I'll have a lot of deal flow/experience in underwriting. Also, we have a lean credit team -- only 5 credit analysts currently, so no one is specialized.

Typically after the 2 years in credit you move to a loan officer, but I want to try and move to corporate banking,

Background: 3.0GPA at SEC school. I plan on joining a banking association in my city to network and other orgs if possible. I also plan to get an MBA later on.

How should I go about making myself more appealing to break into corporate banking?

Should I shoot for corporate banks outside the top?
Should I try and lateral into a bigger commercial bank, then move from there?
Should I stick out 2 years of credit analysis before making the switch? Or start looking early on into my first year?

This might sound stupid, but: would a headhunter possibly help me find openings in corporate banking once I've done my time in credit? I'm fine with taking steps back so that I can work at a better firm.

Any recommendations?

Sorry for the rambling, I'm speeding extremely hard
