Lionel used twin can motors in both their standard gauge Hiawatha and Commodore Vanderbilt 4-6-4's, so the engineering exists. What I am proposing is a LARGER Hudson style loco to match the LARGE "Showroom" cars. This engine would likely require minimum O84 radii curvature (as do the "Showroom" cars) to look right. Such a set in Blue Comet livery would be mind-blowing.
Hey, a fellow can dream.....
