An interesting question. I think that you can,PROVIDED you have the required visual reference(Rwy01) by-and do not continue below- the ILS approach ban point OR your circling minima whichever is the HIGHER. Assuming,the visual references are aquired by the higher of the two,you can continue at(or descend to)circling minima but must keep the runway or its' environment in sight at all times throughout the circling manouvre.You cannot descend from your circling MDA unless you have visual contact with the landing runway itself.
