The theory sounds good. I would be sure to really really clean the bleading nipple to prevent any foreign debries being swept into your hydraulic system. The only other difference is that I am not sure that this method would result in new & clean fluid replacing the old fluid.

Any moisture in the brake system will pool at the low point which is the wheel cylinder. Pumping fluid in from the wheel cylinder will contaminate the whole system. Using one of the Vacuum type devices (OTC makes one) would be much wiser. If all the parts are working as they should there is no reason why the bleeding instructions in the shop manual should not work adequately.
Prior to us supplying only Lucas-Girling hydraulic parts i found that there was a very large failure rate of after market CB master cylinders. Mode of failure involved the inability of the piston to return completely to the "at rest" position. This made it impossible to bleed the air from the system. If you have fitted an after market CB master view it with suspicion.
Also, check the anchors at the base of the backing plate that the shoes pivot out from. These should be secure to the backing plate, tap them lightly with a hammer to make sure they are not loose. If these are loose you will never get the brakes to work. Check your master cylinder push rod length and for wear in the pivot of the pedal tower. You may not be getting a full stroke of the piston.
Good luck,
