I don't know your background, but many MBAs at the low/unranked non-GMAT schools go into functional or specialised roles. Many Aston alumni with MBAs are working in business development, marketing, finance or operations, for example rather than in senior management roles. I could imagine that, for example, going to a top business school might give you a similar or better outcome. I am thinking of the MEB at ESCP Europe, a MSc from Imperial, Warwick or Cass. or perhaps the best option would be the Cranfield MSc in Finance and Management.
I don't understand what you mean by "an MSc after an Engineering degree is not usually accepted". Some MSc programmes in the German-speaking region are aimed at people with prior business degrees, but in the UK they are certainly open to engineering graduates.
