bonobo, I would suggest that you avoid existing systems. Any analysis will be with hindsight. The original design and constraints at the time might not be known and thus any critique could be misjudged, altered by history, and refuted by operational experience.
You could consider a more futuristic and wide ranging analysis covering many of the subjects which you suggest; play to your strengths.
As an example consider the analysis at

Such a review provides scope for new operational requirements, evolving technologies, human performance, and environmental issues.
Think ahead: the report was dated 1974, but the two aircraft types which evolved from this are still in operation - 40 years!
