Possible to downgrade degree earned from MBA to Masters?

Odd question.

I was in a masters of accounting program at a small private Catholic college that I also went to for undergrad in order to gain eligibility to take the CPA exams. I met all of the requirements to earn the masters in accounting degree however I finished with a MBA with a concentration in accounting (had the opportunity to do an internal transfer after 12 hours with a high GPA).

I'm worried now that my decision to get the MBA instead of the masters in accounting will harm my chances of getting into a top-20 MBA program or even make me ineligible. Since I met all of the requirements for a masters in accounting is there any way to officially have the degree be awarded as that instead of the MBA with accounting concentration? Keep in mind this is 5 years later.
