Even if you get around the frame and route the vacum tubes and get the carb in, you may end up with more of a mess. Quite possibly the biggest thing to overcome is the way the fuel tank sits. Carburated bikes have the fuel tank above the carb and the fuel siphoned into the carburator bowl. The way the gas-tank sits on our bikes the fuel is pumped up to the injector (as with all injected bikes) The carb may need a pump or fuel tank raised.
