Dilemma IB

Hi guys,

Im facing currently a big dilemma:
I am graduating from my MSc in Finance program soon, its the one from Corvinus University Budapest (2 yrs). I am also participant of the CEMS program, thats reputation is very good in Europe. However, I would really like to work in M&A, most likely in London at one of the big IBs, and its definitely not just a current infatuation.
I am considering in order to achieve that to do a 2nd MA or Msc in Finance somewhere in Europe, because I doubt that my university is well-known in the London's IBs. Do you guys think that this is a good idea??? The time I finish that I will be roughly 26-27. CFA is also among my plans. My prospective universities would be RSM, St. Gallen, maybe LSE. I did some internships in commercial banks and consulting in Hungary.

I would really appreciate your help guys and your opinions!
