Not really. This entire problem stems from the fact that the original 737 was an aircraft designed to compete with the DC-9 and was built low to the ground to service small regional airports which lacked boarding bridges. The fuselage is not the relevant component in question here (although from a passenger comfort perspective, the lower floor of the 757 vs the 737 makes the cabin feel much roomier and doesn't place the windows at one's hip like a CRJ), it's the configuration of the landing gear, wing design, flight characteristics, etc. Now many of these have been altered over the numerous generations of the 737, however they are still severely limited with the airframe. The last model of 737 realistically should have been the 737-500, the NG should have been a completely new aircraft if Boeing had really wanted to outpace Airbus. The NG was where the 737 really started to be pushed far beyond anything it was really even envisioned to be.
Oh, and on a side note, a four cylinder engine really doesn't have any business being in a true SUV.
