Time spent trying to fit discs would be better spent making the drum brakes work properly. Discs are not much better than well set up drums, and both will lock the wheels at quite low speeds on loose surfaces, brakes can't get any better than a locked wheel.
Remove the drums, check the pistons work, check the adjusters work. Make sure there is no fluid or grease on linings, roughen linings and drum faces with coarse emery.
Discs have their problems too, I find caliper sliders seized on about 25% of bikes I service.
