Sure its possible, but what airline would dish out the dollars to upgrade the interiors? I believe seatback IFE can be installed in the MD
-11, but no airline currently flying them has opted for it.
Most carriers are busy selling their MD
-11s to Fedex, UPS and various other airfreight providers or parking them in the Mojave in exchange for using more efficient aircraft which are easier to maintain.
To conclude, the MD
-11 is quickly fading from passenger services so such a refurbishment is like throwing money into a furnace.
