I dont understand the point the of this question?
Are you asking us if you're goal is reasonable in the eyes of b schools?
Are you asking us should you follow this as a life plan?
Thats up to you and only you
Ask yourself what friends are telling you not to express YOURE goal this way. Are they qualified to give out such advice?
The switch makes absolute sense and doesn't come across as complaining, how will you help engineers? that needs to be addressed.
