I don't know, but I kind of doubt it. Colt has never been really quick on updating and modifying their existing product lines, probably from a financial standpoint. It took the successes of other manufacturer's taking away market share before they felt compelled to do anything about updating their 1911 pistols. Look how long it took them with the Super 38 to go from headspacing on the rim, to headspacing on the case mouth, something custom barrel makers had been doing for a number of years. Also the supported barrels were designed primarily for competition shooters who were pushing the Super 38 to rather dangerous limits in order to make Major power factor. If you were going to do that (frame cut and supported barrel), then chances are you were going to do a lot of other mods to the gun anyways, and Colt wouldn't benefit financially from that either. So why go to the added expenses of design and tool changes to modify an existing model for a relatively small number of competitive shooters, when the majority of your buyers are satisfied with the gun already.
