If your wheels are spinning at the same RPM, wouldn't this cause issues with the actual contact speeds of the wheels being different? It seems to me that the larger center wheels would lose traction often and cause your drivetrain to "skip" or at least decrease the smoothness of the drive.
The very, very small diameter changes required to make this work would have a negligible effect on speed - seriously, this is taking about around 1/16th of an inch off the diameter of a wheel, maybe 1/8 if you're pushing it.
