Resolution:
The answer is Yes, the Panel can be converted, see Instructions below:

****TURN OFF ALL POWER TO PANELBOARD FIRST*****

1. Rotate entire interior assembly (including Main breaker kit) 180 degrees. Remove screws (3/8-16 X 0.75) from hard bus connectors in Main breaker.

2. Remove screws (12-24 X 3-1/8) holding Main breaker to mounting pan, and slide breaker away from the connectors.

3. Rotate Main breaker 180 degrees so the ON and OFF symbols are in the correct location. (ON position must be up.)

4. Move Main breaker lugs to either the line end or load end to receive the incoming conductors. Torque lug mounting screws to 120 IN lbs. (For TOP FEED, the lugs should be located at the ``ON`` end of the breaker. For BOTTOM FEED, the lugs should be located at the ``OFF`` end of the breaker.)

5. Slide main breaker onto connectors, re-attach to mounting pan with 12-24 X 3-1/8 screws (torque = 30 - 40 IN lbs) and re-attach to connectors with 3/8-16 X 0.75 screws (torque = 250 - 275 IN lbs).

6. Detach M/B cover and load end cover from branch section of deadfront.

7. Rotate branch section of deadfront 180 degrees and re-install M/B cover and load end cover. (This is necessary to achieve proper orientation of deadfront labels.)

8. Any sub-feed breaker(s) must also be rotated in a manner similar to the main breaker so on and off symbols are in the correct location. ON position must be up.
