Sounds to me like you just described a 737NG with a 757 cockpit section. I think I recall the 737/727 cockpit section is actually more aerodynamic than the 757 section. Boeing made slight trade off with the 757 so they could have a common 757/767 cockpit.

A shrunken 757 would have been much heavier and more expensive than the 737NG with similar capacity, thus not the most economic solution. Significant shrinks (e.g. A318, 737-600, 747SP) have rarely been successful or sold in more than token numbers for specific niche markets.

Quoting PPVRA (Thread starter): Say Boeing "E-jets" the 757 and gives it a different (smaller) pair of wings, smaller engines, smaller landing gears, and maybe a smaller tail?
Actually, you would probably have to have a LARGER tail. When you shrink the length of an aircraft, you loose part of the moment arm that the rudder acts upon. Thus, you would need a larger control surface to compensate (i.e. 747SP).

Quoting Irish251 (Reply 3): As the 757, when launched, was designated as the -200 series, does this imply that a series 100 had been contemplated but was not favoured by any customer airlines at the time?
Yes there was a -100 design study. The wing was too big and the landing gear was too heavy.
