Would a career in MIS provide me an oppurtunity to Innovatively design systems to meet Organisational needs?

Sure, but at which level? You will likely be working from a higher position right off with your educational background meaning you may or may not be doing the "ground level" work itself but overseeing it, depending on the management team or board of directors that oversees your duties.

At the same time would it provide me oppurtunities in management , if in future I were to decide to pursue a career in management?

I would be as bold as bet you can do this with your current degree and work experience. All you have to do is sell yourself in a job interview.

Best wishes in your goals!
