Yes, I think the best RoI always comes from the best setting. You're right that you would not be a typical candidate at Trium, IMD or Insead. But, it's imaginable that you could get into an EMBA like LBS or Chicago Booth in London, and I think it would be very easy to get into (for example) a Dutch school.
In a Dutch school you would be on a par with the other candidates, and you would not be stretched so much; in a top programme you would have more of a challenge: a better learning experience, a stronger alumni network, better roots in consulting firms, better careers services... and so on. The RoI is much better.
